Gas Piping (for Qualified Service Person)
Gas piping must agree with local codes or to the National Fuel Gas
Code, NFPA 54-1984 and ANSI Z223.1-1984. The gas usage and information is
listed below.
• The gas pressure regulator presets at 3.5 inches of water column pressure
, (.87 KPa) at the gas manifold.
• While the burners are on, the unit will run 100 Cubic feet (2.84 cu.m) at
100,000 BTU’s per hour (29.3 KW)
of natural gas. Make sure your gas sup-
plier can meet this standard.
• Gas piping system ought not to run excess of ½ psig (3.45 KPa).
a) If the gas supply piping system tests at ½ psig (3.45 KPa) or less,
close the manual shutoff valve to isolate that system.
b) If the gas supply piping system tests in excess of ½ psig (3.45 KPa),
disconnect the shutoff valve from that system.
• Before connecting the Beta Max, make sure the gas line is all clear. After
connection, check gas pressure.
• The gas piping system should be able to meet the maximum demand of all
appliances on that line without pressure loss.
• Do not install a regulator to gas supply unless gas line pressure exceeds 5.5”
