WHAT TO DO IF YOU SMELL GAS

GENERAL INFORMATION

This appliance has been tested in accordance with National Safety Standards
for installation and operation as described in this manual.

Please read all the instructions before beginning your installation. Check with your local building
code agency to ensure compliance with local codes. In the absence of local codes the installation
must comply with National Fuel Gas Code ANSI Z22.3.1. In Canada, current CAN/CGA-B149.1 and
B149.2 installation codes.

Installation and repair should be done by a qualified service person. The appliance should
be inspected before use and at least annually by a qualified service person. More frequent
cleaning may be required due to excessive lint from carpeting, bedding material, etc. It
is imperative that control compartments, burners and circulating air passageways of the
appliance must kept clean.

Unpack all parts from cartons carefully inspecting all parts. If any parts are damaged or missing,
contact shipper or dealer immediately.

Do not install this appliance using damaged parts.

GAS SUPPLY

For use with natural gas or propane gas, depending on which option you have ordered. The minimum
inlet gas supply pressure for the purpose of input adjustment:

Natural = Minimum 5.5" Water Column (1.4 kPa) Maximum 10.5" Water Column (2.6 kPa)
Propane = Minimum 11" Water Column (2.75 kPa) Maximum 13" Water Column (3.25 kPa)

a. The supply system should include a manual shut-off valve and union in the line, so that the heater

can be disconnected for servicing.

b. The appliance and its individual shut-off valve must be disconnected from the gas supply piping

system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).

c. The appliance must be isolated from the gas supply piping system by closing its individual manual

shut-off valve during any pressure testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 kPa).

d. A 1/8 inch N.P.T. plugged tapping is provided, for test gauge connection, on the elbow adjacent

to the gas control valve.

Due to high temperatures, the appliance should be located out of traffic and away from
furniture and draperies.

VENTING

The unit is a vented appliance and must be connected to a chimney/flue in accordance with the code,
using the chimney manufacturer's instructions. Minimum connector length is 4'.

This appliance must not be connected to a chimney flue servicing a separate
solid fuel burning appliance.

VENT DAMPER

This appliance may be installed with vent damper device Part No. MD8. Follow installation instructions
for this part. This part is to be installed by a qualified service person.

The vent damper is located in the first section (starter section) of pipe which attaches to the collar of
the appliance. Only this appliance may be served by the vent damper device installed on this unit. The
vent damper device should be inspected annually by a qualified installer.

The thermally controlled vent damper is an energy saving device designed for installation in vents of
listed gas-fired appliances equipped with a draft hood. The damper saves energy by preventing the
escape of heated air through the venting system, when the appliance is not in use.

It has four quadrants of bimetal which remain closed when the appliance is not in operation. Upon
ignition of the appliance, the hot flue gases reach the damper, causing the quadrants to flex, thereby
opening the vent passage within a short period of time. This internal flexing of the bimetal is the only
movement in the damper. No power supply or functional connection with the appliance controls is
required for operation.

Installation of vent dampers can increase the potential for condensation in oversized masonry chim­neys. This is due to poor thermal insulation of the chimney and reduced air movement when the
damper is closed. We recommend that masonry chimneys be lined with materials such as Type B gas
vent, aluminum or stainless steel to reduce the chance of condensation. Most building codes, in fact,
require the lining of chimneys when gas appliances are vented into masonry chimneys.

Minimum connector
length is 48"
