the gas supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig [3.5 kPa] .
The appliance must be isolated from the gas supply piping system by
•
closing its individual manual shutoff valve during any pressure testing of
the gas supply piping system at test pressures equal to or less than 1/2
psig [3.5 KpA].
2.5 GAS PRESSURE REQUIREMENTS
The sportSchwank Series heater is to utilize natural gas only.
The maximum supply pressure must be limited to 14" w.c. (0.5 psi) [35 mb]. If the sup-
ply line pressure is above 14" w.c. [35 mb], then a separate pressure reducing regula-
tor must be installed. The minimum pressure at the inlet to the heater must be equal
to or greater than 6.0" w.c. [15 mb] for natural gas.
The sportSchwank 30 model is equipped with a safety control system (low gas pres-
sure cut-off switch) designed to shut the burner off in the event of inadequate gas pres-
sure (4.5" w.c. [11.3 mb] minimum gas supply line pressure required).
The burner requires the following gas supply conditions to operate:
Natural Gas: Orifice sized for heat content 1000 Btu/cu ft [37.5 Mj/cu m].

NATURAL GAS
1. Install gas line as outlined in Section 2.
2. MOUNTING HARDWARE: The heater manufacturer cannot anticipate all structural
conditions and other wind and weather conditions in which the heater will be mount-
ed or attached:
Mount heaters using non-combustible mounting hardware
•
Ensure the mounting hardware/brackets and anchoring to the structure is of suf-
•
ficient engineering design, strength, quality and workmanship, to support the
weight of the heater and any other loads such as snow accumulation
Provide bracing as required to prevent undue movement of the heater
•
Seismic bracing, if required, must conform to local codes and engineering prac-
•
tices
Use Table 2 and Figure 2 to determine the heater dimensions and weight re-
•
