Propane (Lp) Gas Conversion Instructions - White Mountain Hearth VSM-18-1 Installation Instructions And Owner's Manual

PROPANE (LP) GAS CONVERSION INSTRUCTIONS

1. If applicable, turn OFF gas supply to vented decorative log
set.
2. If applicable, remove gas supply line from vented decorative
log set.
3. For VSM-(18, 24, 30) only, remove Natural gas inlet regulator
from burner assembly.
3. For VSR-(18, 24, 30) only, remove regulator cap and blue
conversion screw from HI-LO knob on gas valve.
4. For VSM-(18, 24, 30) only, install Propane (LP) gas inlet
regulator marked 10.0 onto burner assembly.
4. For VSR-(18, 24, 30) only, install Propane (LP) gas pink
conversion screw into HI-LO knob on gas valve. Assure that
conversion screw is finger tight (refer to Honeywell
conversion instructions which are included in conversion
kit). Install new regulator cap over pink conversion screw.
5. Remove Natural gas main burner orifice from orifice fitting.
Save the Natural gas main burner orifice from the appliance
for future use.
Attention: Use appropriate main burner orifice for
NORMAL input or REDUCED input.
6. Install Propane (LP) gas main burner orifice into orifice
fitting for NORMAL input.
For VSM-18 or VSR-18, install one Propane (LP) gas main
burner orifice marked 41 for 65,000 BTUH input.
For VSM-24 or VSR-24, install one Propane (LP) gas main
burner orifice marked 40 for 75,000 BTUH input.
For VSM-30 or VSR-30, install one Propane (LP) gas main
burner orifice marked 40 for 75,000 BTUH input.
6. Install Propane (LP) gas main burner orifice into orifice
fitting for REDUCED input.
For VSM-18 or VSR-18, install one Propane (LP) gas main
burner orifice marked 49 for 40,000 BTUH input.
For VSM-24 or VSR-24, install one Propane (LP) gas main
burner orifice marked 45 for 50,000 BTUH input.
For VSM-30 or VSR-30, install one Propane (LP) gas main
burner orifice marked 43 for 60,000 BTUH input.
7. Remove pilot tubing from pilot burner.
8. Remove Natural gas pilot orifice from pilot burner. Save the
Natural gas pilot orifice removed from the appliance for
future use.
9. Insert Propane (LP) gas pilot orifice marked 8 into pilot
burner.
14015-1-0903
10. Attach pilot tubing into pilot burner.
11. Connect gas supply line to vented decorative log set.
12. Attach R-1322, conversion label and R-1321, gas conversion
label to the 4 3/4" x 7 1/4" metal plate supplied in conversion
kit. Attach 4 3/4" x 7 1/4" metal plate to metal chain which
is attached to base assembly.
13. Pressure Testing of the Gas Supply System
a. To check the inlet pressure to the gas valve, a 1/8" (3mm)
N.P.T. plugged tapping, accessible for test gauge
connection, must be placed immediately upstream of the
gas supply connection to the appliance.
b. 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).
c. 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).
Attention! If one of the above procedures results in
pressures in excess of 1/2 psig (14" w.c.) (3.5 kPa) on the
appliance gas valve, it will result in a hazardous condition.
14. Turn on Propane (LP) gas supply to vented decorative log
set.
15. All gas connections must be checked for gas leaks by the
person (qualified agency) making the gas conversion. This
should be done with a soap solution watching for bubbles on
all exposed connections, and if unexposed, a pressure test
must be done.
16. Check the appropriate manifold pressure for the vented
decorative log set according to Gas Supply on Page 8 in this
manual.
17. Check pilot burner flame pattern according to Pilot and
Main Burner Flame Characteristics on Page 12 in this
manual.
18. Check main burner flame pattern according to Pilot and
Main Burner Flame Characteristics on Page 12 in this
manual.
19. Gas conversion is completed.
Attention: The Propane (LP) gas conversion kit must be
ordered from Empire Comfort Systems, Inc.
