Part Description
PSE Pilot Orifice
Main Burner Orifice
SIT Gas Valve Conversion Kit
Gas Conversion Label
Tools Needed: Standard Screwdriver, 1/4" Hex Driver, 5/16" Hex Driver, 3/8" and 1/2" Wrenches
Gas input for direct vent fireplace insert converted to
Propane gas:
DVC20IN71 - 19,500 BTU per hour
DVC26IN71 - 26,000 BTU per hour
DVC28IN71 - 27,500 BTU per hour
The direct vent gas fireplace insert when converted to Propane
gas will have a manifold pressure approximately 10.0" w.c.
(2.49 kPa) at the valve outlet with the inlet pressure to the valve
from a minimum of 10.8" w.c. (2.68 kPa) for the purpose of input
adjustment to a maximum of 14.0" w.c. (3.48 kPa).
INSTRUCTIONS FOR CONVERSION
1. If the fireplace insert is installed, turn OFF gas and electric
supply to fireplace before making gas conversion.
2. Remove barrier screen. Refer to instructions provided with
the fireplace for removal information.
3. Release two glass frame spring clamps at bottom of firebox.
4. Remove glass frame assembly.
5. Remove logs from burner assembly.
6. Remove two 10 x 1/2" screws from rear log support. Remove
log support.
7. Remove four (4) 10 x 1/2" screws from burner/grate base
and one 8 x 1/4" screw from air shutter. Grasp burner/
grate base assembly, lift and pull forward to remove burner
assembly. Use a screwdriver to gently separate the air
shutter from the burner venturi tube at rear of burner.
8. Remove air shutter from orifice fitting. Use a 3/8" and 1/2"
wrench to remove burner orifice.
9. Remove Natural gas main burner orifice from orifice fitting.
10. Install Propane gas main burner orifice into orifice fitting:
for DVC20IN71 USE ORIFICE MARKED 1.30 mm
for DVC26IN71 USE ORIFICE MARKED 53
for DVC28IN71 USE ORIFICE MARKED 1.55 mm
The main burner flame and pilot burner flame must be
checked for proper flame characteristics, as outlined in the
Installation Instructions and Owner's Manual.
Verifying Input Rate of Converted Fireplace
The input of the fireplace must be checked as follows:
1. Turn off all other gas appliances. Clock the gas meter
and determine the number of seconds required to
consume one cubic foot of gas.
2. 3600 ÷ time (in seconds) = cu. Ft. per hour.
3. Then cu. Ft. per hour x heating value of gas = input
rate (Btuh). On installation without gas meters, check
manifold for proper pressure.
