To Switch the Pilot to LP Operation:
(Refer to Figures 26-29)
The pilot assembly in the Bristol is a slide convertible
unit, only requiring access from the firebox and a
7/16” open-end wrench. To convert pilot from NG to
LP:
1. Follow
steps listed in the Installation
Preparation section on page 9 for gaining
access to the firebox and removing the logs.
2. Remove Pilot Shield.
3.
Using the 7/16” wrench, grasp the pilot tower
and turn counter-clockwise about 1/4 turn
(see Figure 27).
4. Look at the front edge of the base of the pilot
tower. You will see the NG/LP Pilot Orifice
Gate protruding toward the front of the pilot
tower and
the letters “NAT” should be visible
on the upper horizontal surface (
see Figure
26).
Slide the gate backward in the Pilot
Tower by pushing on the upturned edge by
the “NAT” lettering until the upturned edge is
flush with the Pilot Tower surface. You will
see the NG/LP Pilot Gate protruding from the
back edge of the Pilot Tower and the letters
“LP” will be visible, separated by a punched
hole.
5.
While holding the NG/LP Pilot Gate in the LP
visible position, grasp the Pilot Tower with the
7/16” wrench and turn clockwise until the
tower is snug. The Pilot Hood should be
oriented such that one pilot flame is directed
at the thermocouple and the other is facing
the main burner
(see Figure 29).
6. Reinstall Pilot Shield.
