Getting Started

A. Design and Installation Considerations

Quadra-Fire 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.

CAUTION

Check building codes prior to installation.

• Installation MUST comply with local, regional, state and
national codes and regulations.

• Consult local building, fi re offi cials or authorities having jurisdic-
tion about restrictions, installation inspection, and permits.

When planning an appliance installation, it’s necessary to
determine the following information before installing:

• Where the appliance is to be installed.

• The vent system confi guration to be used.

• Gas supply piping.

• Electrical wiring.

• Framing and fi nishing details.

• Whether optional accessories—devices such as a fan,
wall switch, or remote control—are desired.

C. Inspect Appliance and Components

WARNING

Inspect appliance and components for damage.
Damaged parts may impair safe operation.

• Do NOT install damaged components.

• Do NOT install incomplete components.

• Do NOT install substitute components.
Report damaged parts to dealer.

• Carefully remove the appliance and components from
the packaging.

• The vent system components and trim doors are shipped
in separate packages.

• The gas logs may be packaged separately and must be
fi eld installed.

• Report to your dealer any parts damaged in shipment,
particularly the condition of the glass.

• Read all of the instructions before starting the insta­llation. Follow these instructions carefully during the
installation to ensure maximum safety and benefi t.

WARNING

WARNING

Keep appliance dry.

• Mold or rust may cause odors.

• Water may damage controls.

B. Tools and Supplies Needed

Before beginning the installation be sure that the following
tools and building supplies are available.

Reciprocating saw Framing material
Pliers Noncorrosive leak check solution
Hammer Gloves
Phillips screwdriver Framing square
Flat blade screwdriver Electric drill and bits (1/4 in.)
Plumb line Safety glasses
Level Tape measure
Manometer Voltmeter
1/2 - 3/4 inch length, #6 or #8 Self-drilling screws
Caulking material (300ºF minimum continuous exposure rating)

Hearth & Home Technologies disclaims any
responsibility for, and the warranty will be voided
by, the following actions:

• Installation and use of any damaged appliance or vent
system component.

• Modifi cation of the appliance or vent system.

• Installation other than as instructed by Hearth & Home
Technologies.

Quadra-Fire • Expression 36 (QV36A-FB) • 2062-900 Rev. S • 11/116

D. Inspect Firebox

Surface cracking or crazing of fi rebrick material is normal
and expected. The following types of cracks are acceptable
and do not require replacement of the unit or the fi rebox:

• Cracks that do not propagate entirely through the

material.

• Light fracture lines or “spider-webbing” on the surface of

the material.

• Cracks that are less than 1/32 in. wide and less than 3

in. long.

• If cosmetically unacceptable, such cracks may be

repaired with the SRV-PACK service kit. See Service
Parts List.

Cracks that are unacceptable:

• Cracks greater than 1/32 in. wide and 3 in. long are at

risk of growing.

• Cracks that penetrate entirely through the firebrick

material.

Inspection for cracking should be run when the appliance
is cool. Cracks tend to close as the appliance heats up.

B. Constructing the Appliance Chase

A chase is a vertical boxlike structure built to enclose the
gas appliance and/or its vent system. Vertical vents that
run on the outside of a building may be, but are not re­quired to be, installed inside a chase.

Construction of the chase may vary with the type of build­ing. These instructions are not substitutes for the require­ments of local building codes. Local building codes MUST
be checked.

Chases should be constructed in the manner of all out­side walls of the home to prevent cold air drafting prob­lems. The chase should not break the outside building
envelope in any manner.

Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.

To further prevent drafts, the wall shield and ceiling
fi restops should be caulked with caulk with a minimum
of 300ºF continuous exposure rating to seal gaps. Gas line
holes and other openings should be caulked with caulk
with a minimum of 300ºF 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.

Diagonal runs have both vertical and horizontal vent as­pects when calculating the effects. Use the rise for the
vertical aspect and the run for the horizontal aspect (see
Figure 5.1).

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 (216 mm)
inches horizontal run and 8-1/2 (216 mm) inches vertical
run. A length of straight pipe is allowed between two 45º
elbows (see Figure 5.1).

C. Measuring Standards

Vertical and horizontal measurements listed in the vent
diagrams were made using the following standards.

1. Pipe measurements are shown using the effective length
of pipe (see Figure 5.2).

2. Measurements are made from the appliance outer wrap,
not from the standoffs.

3. Horizontal terminations are measured to the outside
mounting surface (fl ange of termination cap) (see
Figure 4.1).

4. Vertical terminations are measured to bottom of termi­nation cap.

5. Horizontal pipe installed level with no rise.

B. Wall Penetration Framing

Combustible Wall Penetration

Frame a hole in a combustible wall for an interior wall
shield fi restop, (Figure 6.2) whenever a wall is penetrated.
Use same size framing materials as those used in the wall
construction. The wall shield fi restop maintains minimum
clearances and prevents cold air infi ltration.

Non-Combustible Wall Penetration

If the hole being penetrated is surrounded by noncombus­tible 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 fi restop is only required on one side and no heat
shield is necessary.

If your local inspector requires the wall shield fi restop on
both sides, then both wall shield fi restops must have a heat
shield attached to them.
