WARNING

fire, burns, explosions, electrical shock and carbon monoxide poisoning.

This fireplace is a decorative gas appliance. This fireplace
must be properly installed by a qualified service person.

CARBON MONOXIDE POISONING: Early signs of
carbon monoxide poisoning are similar to the flu with head­aches, dizziness and/or nausea. If you have these signs, the
fireplace may not have been installed properly. Get fresh air
at once! Have the fireplace inspected and serviced by a quali­fied service person. Some people are more affected by carbon
monoxide than others. These include pregnant women, people
with heart or lung disease or anemia, those under the influence
of alcohol, and those at high altitudes.

Propane/LP gas and natural gas are both odorless. An odor­making agent is added to each of these gases. The odor helps
you detect a gas leak. However, the odor added to these gases
can fade. Gas may be present even though no odor exists.

OUTSIDE COMBUSTION AIR PRECAUTIONS AND RECOMMENDATIONS

Note: The use of outside air for combustion
is optional unless required by building
codes. It is only necessary to supply
outside combustion air to one side of
fireplace. Use model OAC4 combustion
air kit (see page 17).

1. Avoid extremely long runs and numerous
turns in duct leading from fireplace to combus
tion air assembly. These conditions increase
the resistance to free flow of air through duct.

See Figures 11 and 12.

2. Locate combustion air assembly at an exterior
location. Make sure the location cannot be
accidentally blocked. Locate assembly above
snow line to prevent snow from blocking
assembly.

3. Never mount combustion air inlet assembly
in garage or storage area where combus
tible fumes (gasoline) might be drawn into
fireplace.

FIREPLACE INSTALLATION

CHECK GAS TYPE

Use proper gas type for the fireplace you are installing. If you have conflicting gas type, do not install fireplace. See dealer
where you purchased the fireplace for proper fireplace according to your gas type.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

INSTALLATION ITEMS NEEDED

Before installing, make sure you have the items listed below.

• External regulator (supplied by installer) • Tee joint

• Piping (check local codes) • Pipe wrench

A qualified installer or service person
must connect appliance to gas supply.
Follow all local codes.

WARNING

• Sealant (resistant to propane/LP gas)

• Test gauge connection*

• Sediment trap (optional but recomended)

• approved flexible gas line with gas connector (if allowed
by local codes — not provided)

* A CSA design-certified equipment shutoff valve with

NPT tap is an acceptable alternative to test gauge connection.
Purchase the CSA design-certified equipment shutoff valve
from your dealer.

For propane/LP connections only, the installer must supply an external regulator. The external regulator will reduce incoming
gas pressure. You must reduce incoming gas pressure to between 11 and 13 inches of water. If you do not reduce incoming
gas pressure, burner system regulator damage could occur. Install external regulator with the vent pointing down as shown
in Figure 16. Pointing the vent down protects it from freezing rain or sleet.

Clean and/or adjust pilot for maximum flame impingement.
Ensure that the thermocouple connection at the gas valve is fully
inserted and tight.

Disconnect the thermocouple from the valve, place one millivolt

lead wire on the tip of the thermocouple and the other meter lead
wire on the thermocouple copper lead. Start the pilot and hold
the valve knob in. If the millivolt reading is less than 15 mV,
replace pilot assembly.

wires across terminals of switch. If burner comes on, replace
defective switch.If the switch is OK, repeat the same procedure
on remote control If burner comes on, replace remote control.

Place jumper wire across wire at gas valves (terminals marked

TH and TP/TH). If burner comes on, wires are faulty or connec­tions are bad. Replace wire.

B. If pilot flame is not close enough to the thermopile, adjust pilot

flame.

C. Check thermopile wire connections to make sure all are tight

and that the thermopile is fully inserted into pilot assembly.
Check thermopile with a millivolt meter. Connect leads to TP
and TP/TH terminals on the control valve. If meter reading is
below 325 mV, replace pilot assembly.

D. Turn valve knob to “On” and switch to “ON.” Take a reading at

the thermopile leads (TP & TP/TH) on the valve. If the meter
reads greater than 175 mV and the burner does not light, replace
defective valve
