GENERAL INFORMATION

This appliance has been tested in accordance with National Safety Standards and has been certifi ed
by LabTest 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 qualifi ed service person. The appliance should be
inspected before use and at least annually by a qualifi ed 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" Water Column Maximum 10.5" Water Column
Propane = Minimum 10" Water Column Maximum 13" Water Column

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 pip-

ing 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 traffi c and away from furniture
and draperies.

VENTING

The unit is a vented appliance and must be connected to a chimney/fl ue in accordance with the
code, using the chimney manufacturer's instructions.

This appliance must not be connected to a chimney fl ue 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 qualifi ed service person.

The vent damper is located in the mid section of pipe. 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 qualifi ed installer.

The thermally controlled vent damper is an energy saving device designed for installation in vents
of listed gas-fi red 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 a round plate which will remain closed when the appliance is not in operation. Upon ignition
of the appliance, the hot fl ue gases reach the damper, causing the damper plate to thereby open
the vent passage within a short period of time.

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"

The starter section
slips into the unit
collar.

CLEARANCES

CLEARANCES

Make sure that minimum clearances to combustible materials are maintained during installation
including adequate space for the proper operation and servicing of the heater.

The minimum clearances from the appliance to combustibles are shown on fi gures 1 and 2. Place
the appliance on a fl at, solid, continuous serface (i.e. wood, tile, concrete, metal).

NOTE: Ensure that the combustion air opening of the heater is not obstructed. Provision must be
made for adequate combustion and ventilation air, with suffi cient clearances around the opening.
There must be adequate accessibility clearance for servicing and proper operation.

Children and adults should be alerted to the hazards of high surface temperature and
should stay away to avoid burns or clothing ignition. Young children should be carefully
supervised when they are in the same room as the appliance. Toddlers, young children,

and others may be susceptible to accidental contact burns. A physical barrier is recom­mended if there are at-risk individuals in the house. To restrict access to a fi replace or
stove, install an adjustable safety gate to keep toddlers, young children, and other at-risk
individuals out of the room and away from hot surfaces.

Any safety screen or guard removed for servicing an appliance must be replaced prior
to operating the appliance. If the barrier becomes damaged, the barrier shall be replaced

with the manufacturer’s barrier for this appliance.

Clothing or other fl ammable material should not be placed on or near the appliance.
