The SIR series is designed for wood shops and features a vacuum combustion system that minimizes leakage. It is not a sealed or direct-vent unit. Residential installations must be vented outdoors, while commercial setups can use direct or indirect venting. This system is unsuitable for elevations above 5,000 feet.

What is required to connect to natural gas
1 answer-
ProductExpert11· a year ago
All gas supply lines must be located in accordance with the required clearances to combustibles from the heater as listed on clearance label of the heater. Installation must be set up per local codes and ordinances. An approved flexible connector is required for connections between the rigid piping and the heater. This should be installed before the control box. An approved shut off valve should be installed with in 6 feet of the union. The gas pipe, flexible hose and connections must be self supporting. The gas pipe must not bear any of the weight of the heater. The heater will require either the horizontal 4" vent kit item number 29794 or vertical kit item number 28795. The thermostat relay kit item number 16289 is also recommended for the heater. Installation instructions are included with the heater.
