2 Getting Started
A. Design and Installation Considerations
Heat & Glo direct vent gas appliances are designed to
operate with all combustion air siphoned from outside of
the building and all exhaust gases expelled to the outside.
No additional outside air source is required.
Installation MUST comply with local, regional, state and
national codes and regulations. Consult insurance carrier,
local building inspector, fire officials or authorities having
jurisdiction over restrictions, installation inspection and
permits.
Before installing, determine the following:
• Where the appliance is to be installed.
• The vent system configuration to be used.
• Gas supply piping.
• Configuration of the required PowerFlow™ Heat
Management System(s). See Section 6.C.
• Electrical wiring requirements.
• Framing and finishing details.
• Which required power vent system will be used: PVI-
SLP-B or PVLP-SLP.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. For
assistance or additional information, consult a qualified
service technician, service agency or your dealer.
WARNING! Risk of Fire! PRIMO models must be power
vented using PVI-SLP-B or PVLP-SLP and have a
PowerFlow™ Heat Management System installed and
operating when the appliance is turned on. Failure to
vent properly could cause overheating and fire.
Installation and service of this appliance should be performed by
qualified personnel. Hearth & Home Technologies recommends
HHT Factory Trained or NFI certified professionals.
Notes Regarding Passive Heat Option
• Approved for use with these models ONLY: PRIMO48,
PRIMO48ST, PRIMO60, PRIMO60ST.
• Approved for use ONLY with Clean Face Finishing
Option.
• Hearth & Home Technologies recommends the PVLP-
SLP power vent option for use with the Passive Heat
Kit. If the application does not allow for the PVLP-
SLP to be used, the PVI-SLP-B may be used. The
PVI-SLP-B must be mounted outside the chase due
to the higher noise level created.
• Because the Passive Heat option is naturally drafted,
it is the only PowerFlowTM Heat management system
that operates automatically when the appliance is
turned on.

C. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield
firestops and construction of the chase may vary with the
type of building. These instructions are not substitutes
for the requirements of local building codes. Therefore,
you MUST check local building codes to determine the
requirements to these steps.
NOTICE: When installing a sprinkler head in a fireplace
chase, it is recommended to use a sprinkler head with a
sprinkler activation temperature classified as Extra High.
Keep sprinkler head away from vent and chimney.
Chases should be constructed in the manner of all out-
side walls of the home to prevent cold air drafting prob-
lems. The chase should not break the outside building
envelope in any manner.
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infiltration may be an issue, the inside surfaces may be
sheetrocked and taped (or an equivalent method may be
used) to achieve maximum air tightness.
To further prevent drafts, the wall shield and ceiling fire-
stops should be caulked with caulk with a minimum of
300 ºF continuous exposure rating to seal gaps. Gas line
holes and other openings should be caulked with caulk
with a minimum of 300 ºF continuous exposure rating or
stuffed with unfaced insulation. If the appliance is being
installed on a cement surface, a layer of plywood may be
placed underneath to prevent conducting cold up into the
room.
D. Floor Protection
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly
on carpeting, vinyl, tile or any combustible material other
than wood.
WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
• Insulation and other materials must be secured to prevent
accidental contact.
• The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and
making contact with fireplace or chimney.
• Failure to maintain airspace could cause overheating
and fire.
Note: Figure 3.7-Figure 3.10 show the fireplace installed on
the floor. However, this fireplace can be elevated off the floor
provided that the fireplace is properly supported by framing
materials and the ceiling clearances are maintained.

E. Measuring Standards
Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards:
• Pipe measurements are shown using the effective length
of pipe. See Section 12.A for information on effective
length of pipe components.
• Measurements are made from the factory-installed 6 inch
DVP pipe, not from the standoffs.
• Horizontal terminations are measured to the outside
mounting surface (flange of termination cap). See
Figure 4.3.
• Vertical terminations are measured to bottom of
termination cap.
• Horizontal pipe installed level with no rise.
General Rules:
• When penetrating a combustible wall, a wall shield
firestop must be installed.
• When penetrating a combustible ceiling, a ceiling firestop
must be installed.
• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.
• The PRIMO must be power vented using either a PVI-
SLP-B system or a PVLP-SLP system.
F. Vent System and Diagrams
C. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP or SLP venting systems. Refer to Sec-
tion 12.A for vent component information and dimensions.
DO NOT mix pipe, fittings or joining methods from differ-
ent manufacturers.
The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each
joint within the wall.
WARNING! Risk of Fire or Asphyxiation. This appli-
ance requires a separate vent. DO NOT vent to a pipe
serving a separate solid fuel burning appliance.
D. Use of Elbows
Diagonal runs have both vertical and horizontal vent as-
pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect (see
Figure 4.4).
Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216
mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A
length of straight pipe is allowed between two 45º elbows.

PVI-SLP-B Baffle Adjustment
Figure 4.6 PVI-SLP-B Baffle Indicator
The PVI-SLP-B has a baffle adjustment which must
remain set in the closed position. This baffle adjustment
is located alongside the motor. The baffle adjustment
is measured using the holes on the indicator bar of the
PVI-SLP-B baffle. This bar raises as the baffle is opened
and lowers as the baffle is closed. When only one hole is
showing, the baffle is closed. The PRIMO requires that
the baffle MUST remain set in the CLOSED position as
indicated in Figure 4.6.

B. Wall Penetration Framing/Firestops
Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield firestop(s). The wall shield
firestop maintains minimum clearances and prevents cold
air infiltration.
• The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
• SLP pipe - A wall shield firestop must be placed on each
side of an interior wall. A minimum 1-1/2 in. (38 mm)
overlap of attached heat shields must be maintained.
• DVP pipe - A wall shield firestop is required on one side
only on interior walls. If your local inspector requires a
wall shield firestop on both sides, then both wall shield
firestops must have a heat shield (refer to Section 12.A.)
attached to them.
• See instructions included with PVLP-SLP and PVI-SLP-
B for clearance information.
• See Section 7.F. for information for regarding the instal-
lation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-com-
bustible materials such as concrete, a hole with diameter
one inch greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield firestop is only required on one side and no heat
shield is necessary.

C. PowerFlow™ Heat Management
Introduction
PowerFlow™ Heat Management Systems allow the heat
from the PRIMO appliance to be redirected as desired.
At least one PowerFlow™ Heat Management System is
required on all PRIMO installations and must be installed
by a qualified service technician at the time of the appli-
ance installation. Follow the instructions shipped with the
kit for installation and operation.
Prepare For Heat Management
NOTICE: Additional clearances are required for heat
management systems installations. Provisions must be
made in advance to ensure fit within the framing.
• Determine the heat management system(s) that will be
installed.
• Remove the appropriate seal plate(s).
• Center the duct collar around the exposed hole and
attach it to the appliance.
Note: Do this BEFORE final positioning of the appliance.
• Determine the location for the air register/fan housing
assembly.
Reference the appropriate instructions included with
the PowerFlow™ Heat Management System kit for the
remaining installation steps.
PowerFlow™ Heat Management System options are:
• HEAT-ZONE-PRIMO: The heat is diverted into an
adjacent room.
• HEAT-OUT-PRIMO: The heat is diverted outside the
home/building.
• PRIMO Passive Heat (PHFR-PRIMO-48 / PHFR-
PRIMO-60 / PHSI-PRIMO): The heat is vented into
the room in which the appliance is installed through
a discharge opening(s). This option is available for
PRIMO48, PRIMO48ST, PRIMO60 and PRIMO60ST
models only.
At least one of these options must be installed and in
operation whenever the appliance is turned on.
The PRIMO may utilize two PowerFlow™ Heat
Management Systems, but not all are compatible. The
HEAT-OUT-PRIMO kit may be used with either HEAT-
ZONE-PRIMO or one of the Passive Heat options. HEAT-
ZONE-PRIMO can not be used with either of the Passive
Heat options. The dedicated seal plates, as shown in
Figure 6.3, must be used only as indicated.
WARNING! Risk of Fire! DO NOT block PRIMO Passive
Heat discharge openings! Overheating of appliance and
combustible materials will occur.

D. Securing and Leveling the Appliance
WARNING! Risk of Fire! Prevent contact with:
• Sagging or loose insulation
• Insulation backing or plastic
• Framing and other combustible materials
Block openings into the chase to prevent entry of blown-
in insulation. Make sure insulation and other materials
are secured.
Failure to maintain air space clearance could cause
overheating and fire.
To properly position, level, and secure the appliance, see
below. Nailing tabs are provided to secure the appliance
to the framing members.
• Bend out the two nailing tabs on each side.
• Place the appliance into position. See note below if
installing Passive Heat option.
• Keep nailing tabs flush with the framing. See Figure 6.4.
• Level the appliance from side to side and front to back.
• Shim the appliance as necessary. It is acceptable to use
wood shims underneath the appliance.
• Secure the appliance to the framing by using nails or
screws through the nailing tabs.
Some figures in manual show the fireplace installed on the
floor. However, this fireplace can be elevated off the floor
provided that the fireplace is properly supported by framing
materials and the ceiling clearances are maintained.
Setting the Fireplace into the Framing
The left and right nailing tabs were designed as a means
to ensure the fireplace is mounted flush with the framing
materials. See Figures 6.4-6.6.
1. The shipping flanges protrude further out from the ap-
pliance than the side standoffs. The shipping flange
may be bent upward or broken off in order to place the
appliance into position in the framing.
2. Bend out all nailing tabs. The see-through model will
have eight nailing tabs. The single-sided model will
have four nailing tabs.
3. Screw each nailing tab to the adjoining framing ma-
terial. Ensure that the one inch air space clearance
is maintained on the sides and back of the fireplace.
See Figures 3.5-3.9 for framing and clearance details.

WARNING! Risk of Asphyxiation! Handle firebox glass
assembly with care. Inspect the gasket to ensure it is
undamaged and inspect the glass for cracks, chips or
scratches.
CAUTION! Risk of Cuts! Wear protective gloves and
safety glasses during installation. Use suction cups to
handle firebox glass.
Note: If a granite surround is installed, the two side
pieces need to be removed in order to access the firebox
glass. See appliance installation manual.
• PRIMO60 AND PRIMO72 MODELS: It is recom-
mended that glass installation and removal be per-
formed by two qualified service technicians.
Removing Firebox Glass Assembly
1. Remove the transition media from the appliance. Lift
the transition media tray out of appliance. The tran-
sition media tray fits tightly, lift carefully. See Figure
11.4.
2. Locate the glass clips that are on the upper edge of
the glass frame of the appliance. See Figure 11.4.
3. Use both index fingers to release the glass clips.
4. Allow glass to tilt forward. Lift up and out. The glass
will lift out of the bottom retaining lip.
Replacing Firebox Glass Assembly
1. Locate retaining lip on lower front face of firebox.
Note: Remove any media that may have fallen into the
glass retaining lip.
2. Place glass assembly into retaining lip. Tilt top of
glass assembly toward fireplace.
3. Assure proper left to right placement of glass and en-
gage all four spring latches.
WARNING! Handle glass with care. Glass is breakable.
Inspect the gasket to ensure it is undamaged and inspect
the glass for cracks, chips or scratches.
• Avoid striking, scratching or slamming glass
• Avoid abrasive cleaners
• DO NOT clean glass while it is hot
• Replace as a complete assembly.
• Prepare a work area large enough to accommodate
firebox glass assembly and barrier glass by placing a
drop cloth on a flat, stable surface.
Note: Firebox glass assembly and gasketing may have
residue that can stain carpeting or floor surfaces.
