B. Installing V ent Components

Before starting installation of vent kits, the installer
should read the Gas Stove Instructions and the Vent
Kit Instructions to ensure that the proper system has
been selected for the installation.

Determine the exact position of the stove so the vent
pipe is centered (if possible) between two building
framing members. This will avoid any extra framing.
Using a level, make sure the stove is properly
positioned and squared. Minimum clearances to walls
and ceilings must be maintained.

Vent terminals should not be recessed into a wall.
Consult your local Building Code Regulations before

beginning the installation.

• The size of the roof hole framing dimensions
depend on the pitch of the roof. There MUST BE
a 1-inch (25.4 mm) clearance from the vertical
vent pipe to combustible materials.

• Mark the roof hole accordingly.

• Cover the opening of the installed vent pipes.

• Cut and frame the roof hole.

• Use framing lumber the same size as the roof
rafters and install the frame securely . Flashing
anchored to the frame must withstand heavy
winds.

• Continue to install concentric vent sections up
through the roof hole (for inside vent installations)
or up past the roof line until you reach the appro­priate distance above the roof (for outside termi­nations).

Step 5
The Gas
Supply Line

Figure 22. Gas Controls Systems
NOTE: Have the gas supply line installed by a

qualified service technician in accordance with all
building regulations.

NOTE: Before the first firing of the stove, the gas
supply line should be purged of any trapped air.

NOTE: Consult local building regulations to
properly size the gas supply line leading to the
1/2 inch (13mm) hook-up at the unit.

This gas fireplace is designed to accept a 1/2 inch
(13 mm) gas supply line.

To install the gas supply line:

• A listed 1/2 inch (13 mm) manual shut-of f valve and
a listed flexible gas connector are connected to the
1/2 inch (13 mm) inlet of the control valve.

• A 1/8 inch (3 mm) N.P.T. plugged tapping, accessible
for test gauge connection, should be provided for in
the gas supply line leading to the unit’s shut-off valve.

• Locate the manaul shut-off valve at the rear of the stove.

• Connect the gas supply line to the shut-off valve.

• When attaching the pipe, support the control so that
the lines are not bent or torn.

• After the gas line installation is complete, use a soap
solution to carefully check all gas connections for leaks.

A one-eighth (1/8) inch (3 mm) N.P.T. plugged tapping
is provided on the outlet side of the gas control for a
test gauge connection to measure the manifold
pressure. To measure inlet pressure, provisions must
be made to attach a test gauge to a one-eighth (1/8)
inch (3 mm) N.P.T . plugged tapping immediately
upstream of the gas supply connection to the
fireplace. On some models there may be a tap for the
manifold and inlet pressure on the face of the valve.
Use a small flat blade screwdriver to crack open the
screw in the center of the tap. Position a rubber hose
over the tap to obtain the pressure reading.

25

The fireplace and its individual shut-off valve must
be disconnected from the gas supply piping system
during any pressure testing of the system at test
pressures in excess of one-half (1/2) psig (3.5 kPa).

The fireplace must be isolated from the gas supply
piping system by closing its individual shut-off valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than one­half (1/2) psig (3.5 kPa).

Step 9
Installing Logs
and Ember
Material

Positioning the Logs

If the gas logs have been factory installed they should
not need to be positioned.

If the logs have been packaged separately , refer to the
installation instructions that accompany the logs.

Save the log instructions with this manual.

If sooting occurs, the logs might need to be repositioned
slightly to avoid excessive flame impingement.

Placing the Ember Material

Two separate bags of ember material are shipped with
this gas fireplace:

• The bag labeled Golden Ember (GE-93) is flame
colorant material.

• The bag labeled Glowing Ember (050-721) is
standard glowing ember material.

To place the ember material:

• Remove the glass door from the unit.

• Cover the top of the burner with a single layer of em­ber material. Then sprinkle GE-93 on top of the burner .

• Save the remaining ember materials for use during
fireplace servicing.

• Replace the glass door and a front trim door on the
unit (see Replacement Parts Section of the manual.)

27

1. Place the ember
material directly
onto the top of the
burner.

Step 10
Before Lighting
the Stove

Before lighting the stove, be sure to do the following:
Review safety warnings and cautions

• Read the Safety and W arning Information section
at the beginning of this

Double-check for gas leaks

• Before lighting the stove, double-check the unit for
possible gas leaks.

Double-check vent terminations for obstruc­tions.

• Before lighting the stove, double-check the unit for
possible obstructions that could be blocking the
vent terminations.

Double-check for faulty components

• Any component that is found to be faulty MUST BE
replaced with an approved component. Tampering
with the stove components is DANGEROUS and
voids all warranties.

A small amount of air will be in the gas supply lines.
When first lighting the stove, it will take a few minutes
for the lines to purge themselves of this air. Once the
purging is complete, the stove will light and will
operate normally .

Installers Guide

.

Step 11
Lighting the
Stove

After the
Installation

Subsequent lightings of the stove will not require this
purging of air from the gas supply lines, unless the
gas valve has been turned to the OFF position, in
which case the air would have to be purged.

You’ve reviewed all safety warnings, you’ve checked
the stove for gas leaks, you know the vent system is
unobstructed, and you’ve checked for faulty
components. Now you’re ready to light the stove.
