CONVERTING VALVE KITS FROM NATURAL TO LP (PROPANE) GAS
NOTE
: When converting a vented log set from NATURAL to LP (PROPANE) it will be necessary to use the LPK-18 or
LPK-24. The LPK-18 is used for 18-inch or smaller logs sets and the LPK-24 is used for 24 to 30-inch log sets.
The
AFVK-SPLIT VALVE SYSTEMS
use electronic control valves that are convertable from Natural to LP gas by a
Simple Rotary Knob
located on the front
“face”
of the gas valve (See figure 13).
1.
Remove the black metal cover from the front of the Valve Box to access the
“face”
of the control valve.
2.
Unscrew the aluminum cap on the front of the gas valve (See figure 12). Note
the position of the marker on top
of the rotary knob shaft. This mark will point to NAT or LP indicating the type of gas the valve is currently set.
3.
To convert the valve from the factory setting (NAT) gently push the rotary knob inward with two fingers and rotate
left or right to the LP position (See figure 13).
NOTE
: The marker will now point to LP and the shaft will stay
recessed inward.
4.
To convert the valve back to the factory setting (NAT) push in the rotary knob and rotate back to NAT.
NOTE
: the
marker will now point to NAT and the shaft will remain in the outward position.
5.
After the conversion has been made check the outlet pressure with a manometer (main burner must be ON).
The factory setting on the internal regulator is 3.5”WC Natural and 10.5”WC LP.
6.
Replace the aluminum cap.
NOTE
: See the LPK-18 or LPK-24 instructions to convert the burner pan to LP gas this involves installing an orifice air
shutter, pilot orifice and media (removing sand and using vermiculite for LP gas).
SPECIAL FEATURES OF THE VALVE KIT ELECTRONIC MODULE
All valve kits modules have (2) special features built into the system as follows:
1. CONTINUOUS PILOT FEATURE:
The AFVK-SPLIT valve kits have a Continuous Pilot feature that may be activated in cold
climate conditions or to maintain a draft in the chimney. The continuous pilot can be activated
by the following two methods.
Off/Continuous Pilot Switch on Front of the Switch Box
The Continuous Pilot feature may be activated by placing the ”Off/Continuous Pilot” switch
located on the front of the Switch Box in the “Continuous Pilot” position. See figure 15. When
this switch is turned to the Continuous pilot position the pilot will immediately spark to light the
pilot and the pilot will remain ON.
