Installation Instructions

IMPORTANT INFORMATION
This kit provides control over the unit gas valve by routing the
gas valve wiring through the supplied pressure switch. To en-
able proper fit-up, the pressure switch kit must be installed
before connecting the gas supply line to the gas valve. For
new unit installations, the kit hardware may be fitted to the gas
valve while the gas manifold is removed for LP gas orifice
conversion. For existing installations, the gas valve line must
be disconnected from the gas valve to allow fitting of kit hard-
ware. Refer to Figures 2, 3, 4, 5 or 6 for a view of kit hardware
as installed in unit. Before proceeding, shut off gas supply
at manual shutoff and turn off power to unit.
Contact a local propane gas supplier
about installing a gas detecting warning device.
