PROPANE/LP VENT-FREE FIREPLACE SYSTEM

CONNECTING TO GAS

SUPPLY

WARNING: A qualified ser-

vice person must connect fire-

place to gas supply. Follow all

local codes.

CAUTION: Never connect fire-

place directly to the propane/LP

supply. This fireplace requires

an external regulator (not sup-

plied). Install the external regula-

tor between the fireplace and pro-

pane/LP supply.

CAUTION: Use only new,

black iron or steel pipe. Inter-

nally-tinned copper tubing may

be used in certain areas. Check

your local codes. Use pipe of 1/2"

or greater diameter to allow

proper gas volume to fireplace. If

pipe is too small, undue loss of

volume will occur.

The installer must supply an external regu-

lator. The external regulator will reduce

incoming gas pressure. You must reduce

incoming gas pressure to between 11 and

14 inches of water. If you do not reduce

incoming gas pressure, fireplace regulator

damage could occur. Install external regu-

lator with the vent pointing down as shown

in Figure 23. Pointing the vent down pro-

tects it from freezing rain or sleet.

Attaching Wood Base to Solid

Floor

For attaching base to solid floors (concrete

or masonry)

Note:

Floor anchors and mounting screws

are in hardware package. The hardware pack-

age is provided with fireplace.

1. Drill holes at marked locations using

5/16" drill bit. For solid floors (concrete

or masonry), drill at least 1" deep.

2. Fold floor anchor as shown in Figure 22.

3. Insert floor anchor (wings first) into

hole. Tap anchor flush to floor.

4. Insert mounting screws through base

and into floor anchors.

5. Tighten screws until base is firmly fas-

tened to floor.

Installation must include an equipment

shutoff valve, union, and plugged 1/8" NPT

tap. Locate NPT tap within reach for test

gauge hook up. NPT tap must be upstream

from fireplace (see Figure 24).

IMPORTANT:

Install equipment shutoff

valve in an accessible location. The equip-

ment shutoff valve is for turning on or

shutting off the gas to the appliance.

Check your building codes for any special

requirements for locating equipment shutoff

valve to fireplaces.

Apply pipe joint sealant lightly to male NPT

threads. This will prevent excess sealant

from going into pipe. Excess sealant in pipe

could result in clogged fireplace valves.

* Purchase the optional CSA design-certified

equipment shutoff valve from your dealer. See

Accessories, page 27.

INSTALLATION

Continued

Extension Cord

Use extension cord if needed. The cord must

have a three-prong, grounding plug and a

three-hole receptacle. Make sure cord is in

good shape. It must be heavy enough to carry

the current needed. An undersized cord will

cause a drop in line voltage. This will result

in loss of power and overheating. Use a No.

16 AWG cord for lengths less than 50 feet.

WARNING: This appliance re-

quires a 45° male flare fitting 5/8"-

18 UNF (Unified National Fine

Thread) inlet connection and the

flexible gas line provided.
