INSTALLING DAMPER CLAMP ACCESSORY
FOR VENTED OPERATION

(Remote-Ready Models Only)

Note:

 When used as a vented heater, appliance must be installed

only in a solid-fuel burning fireplace with a working flue and
constructed of noncombustible material.

If your heater is a manually-controlled, you may use this heater as
a vented product. There are three reasons for operating your heater
in the vented mode.

1.

The fireplace does not meet the clearance to combustibles re-
quirements for vent-free operation.

2.

State or local codes do not permit vent-free operation.

3.

You prefer vented operation.

If reasons number 1 or 2 above apply to you, you must permanently
open chimney flue damper. You must install the damper clamp
accessory (to order, see 

Accessories

, page 38). This will insure vented

operation (see Figure 10). The damper clamp will keep damper open.
Installation instructions are included with clamp accessory.

See chart below for minimum permanent flue opening you must
provide. Attach damper clamp so the minimum permanent flue
opening will be maintained at all times.

INSTALLING HEATER BASE ASSEMBLY

 WARNING: You must secure this heater to fire-

place floor. If not, heater will move when you adjust
controls. Moving heater may cause a gas leak.

 WARNING: If installing in a sunken fireplace,

special care is needed. You must raise the fireplace
floor to allow access to heater control panel. This will
insure adequate air flow and guard against sooting.
Raise fireplace floor with noncombustible material.
Make sure material is secure.

 CAUTION: Do not pick up heater base assembly

by burners. This could damage heater. Only handle
base assembly by sides of base.

IMPORTANT:

 Make sure the heater burners are level. If heater is

not level, heater will not work properly. For thermostat models,
avoid damage to thermostat bulb. Avoid nicks or sharp bends in
thermostat bulb wire. Keep thermostat bulb in mounting bracket.

Installation Items Needed

• hardware package (provided with heater)
• approved flexible gas hose and fitting (not provided) (if allowed

by local codes)

• sealant (resistant to propane/LP gas, not provided)
• electric drill with 3/16" drill bit (metal or masonry as applicable)
• flathead screwdriver

1.

Connect fitting to base as shown in Figure 11. Connect approved
flexible gas hose to fitting in base (see Figure 11).

IMPORTANT:

 Hold gas fitting with wrench when connecting

flexible gas hose.
