The heater can be mounted horizontally or up to an angle of 45º maximum from horizontal. When the heater
is to be angle mounted adjacent to a sidewall, make sure the draft inducer assembly is on the lower side of
the heater so that the control box access panel is easily accessible. Make sure the long axis of heater is level.
Multiple draft inducer positions can also be used as shown in the diagrams. This allows for the desired
configuration of flue venting.

1.
Connect to the supply tank or manifold in accordance with the latest edition of National Fuel Gas Code (ANSI
Z223.1), and local building codes. Authorities having jurisdiction should be consulted before the installation
is made. (In Canada, refer to the latest edition of CSA Standard B149.1, Natural Gas and Propane
Installation Code.)
2.
Check that the gas fuel on the burner rating plate matches the fuel for the application.
3.
Check that the gas supply piping has the capacity for the total gas consumption of the heaters and any other
equipment connected to the line.
4.
Check that the calculated supply pressure with all gas appliances and heaters operating will not drop below
the minimum supply pressure required for these heaters. Check inlet supply pressures on Section 12.0).
5.
All gas supply lines must be located in accordance with the required clearances to combustibles from the
heater as listed on the clearances label of the heater and Section 4.0) of this manual.
6.
Pipe joint compounds must be resistant to the action of liquefied petroleum gases.
7.
Tube heaters will expand/contract during operation. Where local codes do not prohibit, a CSA or U.L.
approved flexible connector supplied with this heater is required for connections between the rigid piping
and the heater. A union should be installed before the control box inlet. An approved shut off valve should be
installed within 6 feet of the union.
8.
The gas pipe, flexible hose and connections must be self supporting. The gas pipe work must not bear any of
the weight of the heater or any other suspended assembly.
