BUILDING CODES AND SAFETY STANDARDS
The design of this FIREPLACE ACCESSORY has been tested and is listed with PFS
CORPORATION in accordance with THE AMERICAN NATIONAL STANDARDS
INSTITUTE - ANSI Z21.50, PFS File Number F15-047.
This manual serves only as a basic guideline for installation and use of this firebox
and gas piping. The complete installation must be in accordance with local codes and
ordinances, or, in the absence of local codes, with the American National Standards
Institute National Fuel Gas Code Z223.1 latest edition.
GENERAL INFORMATION
MODELS SF3624/4224-TV ARE TOP-VENTED DECORATIVE GAS APPLIANCES. THEY ARE
DESIGNED TO BURN BY DRAWING COMBUSTION AIR FROM THE ROOM THEY ARE
INSTALLED IN OR THE OUTSIDE AIR KIT THAT ATTACHES TO THE SIDE OF THE UNIT.
THE EXHAUST FLUE GASES ARE TO BE VENTED THROUGH THE TOP-VENT
USING 8" B-TYPE GAS VENT PIPE. ALL-FUEL CLASS A CHIMNEY PIPE MAY ALSO
BE USED.
THE CONTROL SYSTEM IS A MILLIVOLT OR SPARK TO PILOT TYPE THAT
INCLUDES AN ON-OFF SHUT-OFF VALVE, A GAS CONTROL VALVE, A STANDING
PILOT LIGHT ASSEMBLY, PIEZO IGNITOR AND ON-OFF ROCKER SWITCH.
WARNING: THIS UNIT IS NOT FOR USE WITH SOLID FUEL.
NOTE: INSTALLATION AND REPAIR SHOULD BE DONE BY A QUALIFIED SERVICE
PERSON. THE APPLIANCE SHOULD BE INSPECTED BEFORE USE AND AT
LEAST ANNUALLY BY A PROFESSIONAL SERVICE PERSON. MORE FREQUENT
CLEANING MAY BE REQUIRED DUE TO EXCESSIVE LINT FROM CARPETING,
BEDDING MATERIAL, ETC. IT IS IMPERATIVE THAT THE UNITS CONTROL
COMPARTMENT, BURNERS, AND CIRCULATING AIR PASSAGE WAYS BE KEPT
CLEAN TO PROVIDE ADEQUATE COMBUSTION AND VENTILATION AIR.
CLEARANCES REQUIRED
MINIMUM CLEARANCES FOR THE FIREBOX ARE:
1/2" ON THE SIDES AND BACK AND 0 AT THE BOTTOM. TOP CLEARANCE IS 3"
WHICH IS THE HEIGHT OF TOP STANDOFFS, SEE FIGURE 7.1 FOR FRAMING
DIMENSIONS:
NOTE: PROVIDE ADEQUATE CLEARANCES AROUND AIR OPENINGS INTO THE
COMBUSTION CHAMBER.
NOTE: ADEQUATE ACCESSIBILITY CLEARANCES FOR SERVICING AND PROPER
OPERATION MUST BE PROVIDED IN ACCORDANCE WITH ANSI Z21.50 - 2014.

GAS PIPING AND GAS PRESSURE REQUIREMENTS
All gas piping must be installed to comply with local codes, or, in the absence of local
codes, with the latest edition of the National Fuel Gas Code ANSI Z223.1.
Unions in gas lines shall be of ground joint type. Compounds used on threaded joints of
gas piping must be resistant to the action of liquefied petroleum gas. Gas piping must
be of sufficient size to provide a minimum natural gas pressure at the appliance of 7"
water column or 11" for LP gases for the purpose of input adjustment. The maximum
inlet gas pressure to the unit must not exceed 10" for natural gas, and 13" for LP gases.
If this unit is to be supplied with LP gas (bottled propane)the tank or bottle supplying the
gas must have a regulator that reduces the gas pressure to between 11 and 13 inches
water column. The control will not operate with gas line pressure directly from the tank
and may leak gas due to this excessive pressure.
DANGER: OPERATION OF THIS UNIT ON LP GAS WITHOUT AN APPROVED
REGULATOR AT THE SUPPLY CONTAINER WILL LEAD TO GAS LEAKS AT THE
CONTROL WITH POSSIBLE FIRE OR EXPLOSION.
Include a manual shut-off valve and union in the line so the control or heater may be
disconnected for servicing. Include a drip leg and a plugged 1/8" N.P.T. tapping into the
line also. The tapping must be accessible for the test gauge connection immediately
upstream of the gas supply connection to the unit. Use a soap and water solution or
liquid gas leak detector to coat each joint in the piping system and look for bubbles
which indicate gas leaks. Repair all gas leaks.
CAUTION: THE APPLIANCE AND ITS APPLIANCE MAIN GAS 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 PSI (3.5 KPA).
THE APPLIANCE MUST BE ISOLATED FROM THE GAS SUPPLY PIPING SYSTEM
BY CLOSING THE EQUIPMENT SHUTOFF VALVE DURING ANY PRESSURE
TESTING OF THE GAS SUPPLY PIPING SYSTEM AT TEST PRESSURES EQUAL
TO OR LESS THAN 1/2 PSI (3.5KPA).
DANGER: DO NOT USE CANDLES, MATCHES OR OTHER IGNITION SOURCES
WHEN CHECKING FOR LEAKS. FUEL GASES ARE VERY FLAMMABLE AND IN
CERTAIN CONCENTRATIONS, EXPLOSIVE . CHECKING FOR LEAKS WITH AN
OPEN FLAME MAY LEAD TO FIRE OR EXPLOSION.
