Heatmaster Gas Burner User Manual

INSTALLATION AND OPERATING INSTRUCTIONS

IMPORTANT: READ INSTRUCTIONS CAREFULLY BEFORE BEGINNING INSTALLATION OF LOG SET.

NOTE: DAMPER MUST BE OPEN ACCORDING TO CHART ON PAGE 3 OF THESE

INSTRUCTIONS OR FULLY OPEN WHEN LOG SET IS OPERATING.

This burner unit must be installed only in a fully-vented, solid-fuel burning fireplace with a working flue and constructed of
noncombustible material. The damper and chimney must be free of any obstructions. This log set is designed to burn with a
smoky, yellow flame and must be vented for this reason. The fireplace chimney must have a permanent vent opening to the
atmosphere of not less than the minimum square inches stated in Table 1 and Table 2 on page 3 of these instructions. If it is
smaller, do not use this log set.

IMPORTANT: Ensure that the chimney draft is adequate by holding a lit match or candle at the top edge of the fireplace

opening. This will indicate if air movement is toward the fireplace. If draft is inadequate, do not operate logs until draft is
adequate. If you smell fumes from the burner in the room when the damper is fully open, it indicates that the fireplace draft

is insufficient. If the draft is insufficient, have the chimney inspected by a qualified chimney sweep.

DO NOT OPERATE

LOGS UNTIL THE FIREPLACE DRAFT IS CORRECTED. Do not burn solid fuels in a fireplace where a

decorative appliance is installed.

+ Open damper according to the chart on page 3 of these instructions (or fully open) and be sure damper stop clamp is

installed. (See damper stop instructions listed on page 5.) Gas supply pipe must be 1/2” minimum I.D. or larger
(3/4” if gas line is longer than 20 feet). The minimum inlet gas supply pressure for the purpose of input adjustment is
7 inches for natural gas and 11 inches for LP gas. The maximum inlet gas supply pressure is 10.5 inches for natural
gas and 13 inches for LP gas.

+ Solid fuels shall not be burned in a fireplace where a decorative appliance is used.

+ The installation and provisions for combustion and ventilation air must conform with the National Fuel Gas Code,

ANSI Z223.1.

+ The appliance and its individual shutoff 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).

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

+ KEEP APPLIANCE AREA CLEAR AND FREE FROM COMBUSTIBLE MATERIALS, GASOLINE AND OTHER

FLAMMABLE VAPORS AND LIQUIDS.

+ Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect

the appliance and to replace any part of the control system and any gas control which has been under water.

VENTING SYSTEM MAINTENANCE

An annual examination and cleaning of the venting system by a qualified person is recommended.

CLEANING YOUR GAS LOG SET

Periodically you may want to remove the soot build-up on the logs by lightly brushing the logs with a soft brush. Also,
occasionally, visually inspect your burner pan and pilot for proper operation (Fig. 1 and Fig. 2 below).

HOW TO INSTALL YOUR GAS LOG SET

This log set must be installed by a qualified person and instructions must be followed exactly to ensure safe operation.

Your log set is packaged in three (3) boxes. The complete burner assembly is packaged in one box and the logs are packaged
in separate boxes.

GENERAL INSTALLATION

These logs require a minimum permanent free opening as stated in the chart on page 3 of these instructions, that must be
provided by either the fireplace chimney or the fireplace damper to vent the gases. The chimney damper must be fixed in a
manner which will maintain the minimum permanent vent opening at all times. This may be accomplished by installing a
screw bolt in the edge of the damper to prevent its closing or by a hole(s) in the damper. These logs must be installed only in
a vented fireplace with a working flue and constructed of noncombustible material. The minimum size fireplace in which
these logs are to be installed is:

BURNER ASSEMBLY AND INSTALLATION

1. Turn off gas supply to fireplace.

2. Ensure that fireplace is clean.

3. Remove complete burner assembly from box and place complete burner assembly on floor of fireplace with the
open side of the bottom pan facing the front of the fireplace.

4. Position the burner assembly centered from side to side and as far toward the back of the fireplace as possible.
The fireplace will draft better with the burner unit toward the back of the fireplace. (Never place the burner

assembly more toward the front in larger fireplaces.)

5. Remove logs from log box and place on burner assembly as described on page 5 under L

og Placement.

6. Visually inspect the position of gas log set in the fireplace as described above.

7. After you have visually inspected the position of the log set in the fireplace, remove logs from burner assembly

and proceed to connect gas supply.

CONNECTING GAS SUPPLY

There is a 3/8 flared fitting installed on your gas log set at the factory. Be sure fittings are the appropriate size on any
tubing that is to be connected to your gas log set. If using tubing that has to be cut and shaped, be sure to use the proper
tubing cutter and flaring tool. Also, be careful not to crimp the tubing when it is being bent to hook up the log set. A crimp in
this line could restrict the gas flow to the log set. If a crimp does occur, do not use the gas line. Gas resistant pipe compound
must be used on all threaded male connections, except brass to brass.

NOTE: During the first 2 to 3 hours of burning, the flame burning against the glowing log will
appear to be orange in color. After this burn in period this flame will turn completely blue and
almost invisible. You will then see mostly glow and no flame on the face of this glowing log,
which enhances the glow appearance.
