GAS CONNECTIONS

GAS LINE INSTALLATIONS
The gas meter should be checked to make sure that it will supply enough gas to the heater and any other appliances that
may be used on the same meter. The gas line from the meter will usually be of a larger size than the gas valve supplied
with the heater. Therefore a reduction of the connecting gas pipe will be necessary. Make this reduction as close to the
heater as possible.
ANSIZ223.1 CSA B149.1 Natural Gas and Propane Installation Codes
A manual main shut-off valve must be installed externally to the heater.
DO NOT INSTALL THE GAS LINE UNION INSIDE THE HEATER CABINET. THIS WILL VOID YOUR WARRANTY.
