STEP ONE: PREPARATION (ALL MODELS) 

 

1.  Verify that the Valve Assembly is correctly matched to the set, burner, 

and gas supply. 

 

2.    Insure that 

Fireplace Gas Supply

 is off (Figure 1A) . 

 

3.  Thoroughly clean fireplace floor of any ashes and have a qualified  

       chimney cleaner insure that the chimney flue and firebox are free of      

       soot, creosote, ashes and loose paint.

(VENTED INSTALLATIONS ONLY)  

Attach 

Damper Clamp 

(Figure 2A) 

over edge of fireplace

Firebox Floor 

In the Commonwealth of Massachusetts: 

• 

Installation must be performed by a licensed plumber or gas fitter. 

• 

The chimney flue damper, when used with gas logs, will be welded open or completely removed. 

• 

A CO detector shall be installed in the room where the appliance is installed. 

VENTED INSTALLATIONS 

 

 

THE CHIMNEY DAMPER MUST BE WIDE OPEN AND FIXED IN A MANNER  TO MAINTAIN A PERMANENT FREE  

OPENING AT ALL TIMES AS OUTLINED ABOVE. THE AREA OF THE FLUE MUST BE NOT LESS  THAN 1/10 THE AREA OF 

THE FIREPLACE OPENING. THIS DECORATIVE GAS APPLIANCE MUST BE INSTALLED IN A FULLY VENTED METAL 

OR MASONRY FIREPLACE WITH A WORKING FLUE THAT IS SAFE FOR BURNING A WOOD FIRE. THE FLUE MUST 

BE FREE OF ANY OBSTRUCTIONS AND MUST EXHAUST ALL PRODUCTS OF COMBUSTION. DAMPER AND GLASS 

DOORS MUST BE FULLY OPEN BEFORE LIGHTING OR BURNING FOR PROPER VENTILATION AND TO  

PREVENT HEAT DAMAGE TO THE VALVE.

 

GENERAL INSTALLATION INSTRUCTIONS 

The installation and the provisions for combustion and ventilation air must conform with 

The National Fuel Gas 

Code ANSI Z223.1 / NFPA54

, or 

The CSA B149.1, Natural Gas and Propane Installation Code, 

latest edition.

 

WARNING! CHECK FOR PROPER VENTING 

A properly sized, unobstructed chimney will normally vent all products of combustion. Any odor or smoke detected inside 

the room is an indication that the flue is not functioning properly.

 

 

SHUT OFF THE BURNER IMMEDIATELY! THE CAUSE OF THE VENTING PROBLEM MUST BE DISCOVERED AND  

CORRECTED BEFORE CONTINUED USE. 

 

Continued use with improper venting may cause damage to your fireplace, room furnishings and could cause serious illness.  

IF IMPROPER VENTING IS SUSPECTED,

 

IMMEDIATELY HAVE THE APPLIANCE AND CHIMNEY FLUE SERVICED.

 

WARNING! 

 

WARNING! 

 

WARNING:  

Failure to position the parts in accordance with these diagrams or failure to use only parts specifically  

approved with this heater may result in property damage or personal injury.

 

LEAK TEST PROCEDURES 

 

WARNING: DO NOT use an open flame to test leaks! 

 

Create a mixture of equal parts soap and water. Apply to all the joints of the pipe fittings from the gas supply to 

the burner. Turn on the gas supply valve for no longer than 3-5 seconds. If bubbles appear in the soap solution 

applied to the joints, there is a leak. Turn off the gas supply valve and tighten those fittings. Repeat the proce-

dure until no more bubbles appear. Test all joints.  NOTE: Always perform a leak test any time the appliance has 

been moved or disconnected from the gas supply line.

 

The minimum permanent free opening of the fireplace chimney or chimney damper must be 

29 sq. inches

 based upon a 

minimum chimney height of at least 10 feet. Solid Fuels shall not be burned in a masonry or UL 127 factory built fire 

place where an 

CHILLBUSTER™ 

is installed.
