Heatilator GCDC60 Installation & Operating Instructions Manual page 12

The gas control valve has been preset at the factory.
Altering settings may result in fire hazard or bodily
injury.
3. Gas Pressure
On the standing pilot and electronic gas control valve, a pressure tap is included on the front face of the valve.
Pressure taps are located on the front face of the valve and accessible for test gauge connection.
Tables 2 and 3 show 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 Hearth & Home Technologies specified and approved parts. In the event your gas appliance must be converted
to use: Propane/standing pilot - CKVP, Natural Gas/standing pilot - CKVN; Propane/intermittent pilot - DCKVP, Natural
Gas/intermittent pilot - DCKVN.
