16. Reattach fireplace floor assembly with

screws removed in step 3 of Removing Fire-

place Screen and Floor Assembly, page 9.

Note:

Discard the remaining hardware items.

After assembly, make sure all wires are com-

pletely clear of blower wheel.

17. Install logs (see Installing Logs, page 24)

and fireplace screen (see Installing Screen,

page 25).

WARNING: Failure to position

the parts in accordance with sup-

plied diagrams or failure to use

only parts specifically approved

with this heater may result in

damage or personal injury.

WARNING: A qualified

service person must connect

fireplace to gas supply. Follow

all local codes.

If any of the original wire as supplied with the

appliance must be replaced, it must be replaced

with 105˚C wire or it's equivalent.
Operating the Blower

After final installation of your fireplace, light your

gas appliance with the blower off. After about 15

minutes, turn the blower on to deliver heated air

at the top louvers. The blower features a variable

control which allows you to select the speed you

desire. In the OFF position, the blower will not

operate. In the ON position, the blower will start

when the thermostat senses a sufficient increase

in firebox temperature (approximately 10 to 20

minutes depending on heat setting).

Your gas logs and thermostat blower will not turn

on and off at the same time. The fireplace may run

for several minutes before the blower turns on.

After the heater modulates to the pilot position, the

blower will continue to run. The blower will shut

off after the firebox temperature decreases.

It is safe to operate fireplace with blower turned

off. However, the blower helps distribute heated

air from the fireplace.
Note:

Periodically check the louvers of the firebox

and remove any dust, dirt or other obstructions.

INSTALLATION

INSTALLING GAS PIPING TO
FIREPLACE LOCATION

WARNING: A qualified

service person must connect

fireplace to gas supply. Follow

all local codes.

WARNING: For propane/LP

units, never connect fireplace

directly to propane/LP supply.

This fireplace requires an external

regulator (not supplied). Install the

external regulator between the

heater and propane/LP supply.

WARNING: For natural gas

units, never connect fireplace

to private (non-utility) gas wells.

This gas is commonly known as

wellhead gas.

Installation Items Needed

Before installing fireplace, make sure you have

the items listed below.

• external regulator (supplied by installer, for

propane/LP units only)

• piping (check local codes)

• sealant (resistant to propane/LP gas)

• equipment shutoff valve *

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

• approved flexible gas line with gas connector

(if allowed by local codes) (not provided)

* A CSA design-certified equipment shutoff valve

with 1/8" NPT tap is an acceptable alternative to

test gauge connection. Purchase the optional CSA

design-certified equipment shutoff valve from your

dealer. See Accessories, page 40.

For propane/LP units, 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 14" of

water. If you do not reduce incoming gas pres-

sure, heater regulator damage could occur. Install

external regulator with the vent pointing down as

shown in Figure 24, page 18. Pointing the vent

down protects it from freezing rain or sleet.
