integral with the gas valve, in the ON
position.
**Optional Control Switches: Wall

Notes:
1. If any of the original wire as supplied
must be replaced, use Type AWM 105°C
- 18 gage wire ONLY.
2. 120 VAC, 60 Hz - Less than 3 Amps.
Caution: label all wires prior to
disconnection when servicing controls.
Wiring errors can cause improper and
dangerous operation.

CAUTION
Ground supply lead must be connected to the wire attached to the green ground screw located on the outlet box. See Figure 47. Failure to do so will result in a potential safety hazard. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70-latest edition. (In Canada, the current CSA C22-1 Canadian Electrical Code).

Step 6. CONNECTING GAS LINE

Make gas line connections. All codes require a

shut-off valve mounted in the supply line. Figure

46 illustrates two methods for connecting the

gas supply. The fl ex-line method is acceptable

in the U.S., however, Canadian requirements

vary depending on locality. Installation must

be in compliance with local codes.

These appliances are equipped with a gas fl ex

line for use (where permitted) in connecting

the appliance to the gas line. A gas fl ex line

is provided to aid in attaching the direct vent

appliance to the gas supply. The gas fl ex line

can only be used where local codes permit. See

Figure 46 for fl ex line description. The fl ex line

is rated for both natural gas and propane gas.

A manual shut off valve is also provided with

the fl ex line.

The incoming gas line should be piped into

the valve compartment and connected (see

Figures 46 & 47). The millivolt control

valve has a 3/8" (10 mm) NPT thread

inlet port. The electronic control valve

has a 1/2" (13 mm) NPT thread inlet port

and is fi tted with a 1/2" x 3/8" (13 mm x

10 mm) NPT fi tting.

Secure all joints tightly using appropriate

tools and sealing compounds (ensure propane

resistant compounds are used in propane

applications).

Optional: Seal around the gas line to prevent

cold air leakage.

Note:The gas supply line must be installed in accor-
dance with building codes by a qualifi ed installer
approved and/or licensed as requed by the locality.
In the Commonwealth of Massachusetts, installa-
tion must be performed by a licensed plumber or
gas fi tter.
