CONVERSION FROM NATURAL
GAS TO LP (LIQUID PROPANE)
Model SB2B is manufactured at the factory for use with
natural gas, and as such requires conversion for use
with an LP gas supply. The conversion should be done
by a qualified technician or your gas supplier. All orifices
required for conversion are provided with the unit.
1. Remove the grate,
burner caps, ven–
turis and burner
bases.
See Figure 4.
2. Remove the burn-
er orifices. Use a
7mm hex socket
on a 3" ratchet
extension and
apply a piece of
foam tape to the
socket to hold the
orifice in the
socket while re-
moving.
See Figure 5.
3. Replace with the
LP orifices supplied
(number 115).
Tighten until snug.
See Figure 6.
4. Reassemble the
burner bases and
venturis. Reinstall
burner caps and
grate.
