Gas Pressure; Gas Conversions - Heatilator GCBC36LE Installation Instructions Manual

3. Gas Pressure

On the standing pilot Gas Control Valve, a pressure tap is
included on the front face of the Valve. The electronic Valve
includes an 1/8" NPT plugged tap on the top and bottom of the
Valve near the outlet to the main burner. Pressure taps are
immediately upstream of the gas supply connection and acces-
sible for test gauge connection.
Table 2 shows optimum gas pressure information.
Consult your local gas company for assistance in determining
the proper orifice for your altitude or refer to ANSI Z223.1-latest
edition, Appendix F.

4. Gas Conversions

Natural or propane gas conversions necessary to meet the
application need to be made by a qualified technician using
Heatilator specified and approved parts.
In the event your appliance must be converted to use propane,
you must use a CKVP Conversion Kit. To convert to use natur-
al, you must use a CKVN Conversion Kit.
