the National Fuel Gas Code, ANsI Z223.1/NFPA54. In
Canada, refer to CAN 1-B146.1.
e. Plugged 1/8" N.P.T. Test Gage Connection is located
on the Heater Gas Control or a N.P.T. Connection is
located on the outside of the Cast Venturi.
2. clearances Minimum clearances to combustibles.
(refer to Figure 1)
Provide adequate clearance to combustibles, Figure 1,
between control end of heater for servicing and mini-
mum on top and sides for ventilation and combustion
air supply.
A minimum clearance of 8' above floor for public
garages in accordance with ANsI/NFPA No. 88 most re-
cent edition or Figure 1; whichever is larger. In Canada
refer to CAN 1-B149.1 Installation codes for Gas burn-
ing appliances.

whichever takes precedence. When installing piping, the following
requirements must be taken into consideration:
• Use new properly reamed black pipe free from chips.
• Apply a good quality pipe compound to all male threads
prior to assembly. If l.P. gas is the fuel, ensure that pipe
