ULTRA FLAME DV “0” Clearance Fireplace
ADJUSTMENTS
NOTE: Adjustments to the valve assembly must be performed by a qualified service person.
• 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 ½ psi
(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 that ½ psi (3.5 kPa).
Natural Gas Pressure Settings:
The inlet supply or line pressure must be a minimum of 5” WC and a maximum of 8” WC. The
orifice has a #36 hole.
ELEVATION INPUT RATING
0 - 2000 ft. 30,000 BTU/hr
2000 - 4500 ft. 30,000 BTU/hr
4500 ft. + 30,000 BTU/hr less 4% per 1000 ft.
or reduce manifold pressure by 0.25” per 1000 ft.
Propane Pressure Settings:
The inlet supply or line pressure must be a minimum of 10.5” WC and a maximum of 12” WC.
The orifice has a #52 hole.
ELEVATION INPUT RATING
0-2000 ft. 26,000 BTU/hr
2000 - 4500 ft. 26,000 BTU/hr
4500 ft. + 26,000 less 4% per 1000 ft.
or reduce manifold pressure by 1” per 1000 ft.
NOTE: THE INPUT RATING SHOULD ALWAYS BE CHECKED WHEN FIRST
RUNNING THIS APPLIANCE. To do this, reduce the background flow rate, time the
meter, light the fireplace and take another reading. Check with your gas supplier for
the gas BTU content at your elevation. Input is the rate of flow multiplied by the
heating value of the gas (cubic feet/hour x BTU per cubic feet). Adjust the manifold
pressure so that the unit does not operate above the rated input.
