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.
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 3.8 and Figure 3.9 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.

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).

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.
For more information regarding installation of the PVI-
SLP-B, refer to the instruction included with that acces-
sory.

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.

by 10 in. (254 mm by 254 mm) whenever
the vent penetrates a ceiling/floor. See
Figure 5.5.
• SLP pipe only - Frame opening 9 in. x 9
in. (229 mm x 229 mm) whenever the vent
penetrates a ceiling/floor.
• Frame the area with the same sized lumber
as used in ceiling/floor joist.
• The ceiling firestop may be installed above or
below the ceiling joists when installed with an
attic insulation shield. It must be under joists
between floors that are not insulated. Refer
to Figure 5.6.

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.

DO NOT penetrate inner pipe.
For 90º and 45º elbows that are changing the vent direction
from horizontal to vertical, one screw minimum should be
put in the outer flue at the horizontal elbow joint to prevent
the elbow from rotating. Use screws no longer than 1/2
inch (13 mm). If predrilling screw holes, DO NOT penetrate
inner pipe.
All outer pipe joints must be sealed with 100% silicone
(300 ºF minimum continuous exposure rating) or alumi-
num foil duct tape, including the slip section that connects
directly to the horizontal termination cap.
• Apply a bead of silicone sealant (300 ºF minimum con-
tinuous exposure rating) inside the female outer pipe
joint prior to joining sections. See Figure 7.1.
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer flues shall be sealed
in this manner, unless otherwise stated.

included with the appliance. The strips would keep the
granite from being installed level. They are required
for the Clean Face finishing method only.
3. A flat sheetrock surface will allow for the granite
surround to sit flat. Sheetrock seams will lead to granite
not being level. See Figure 10.19.

NOTICE: DO NOT install sheetrock trim strips. Granite
pieces will not be level.
The wall and granite pieces must be clean, free from
dust and construction debris, and dry before beginning
installation. Dust or moisture may prohibit the adhesive
from performing effectively.
For the adhesive, choose a 100% silicone or strong
construction adhesive with an aggressive tack intended
to hold heavy material and that also is approved for high
temperatures (250°F minimum).
