Gas Supply
The gas supply to the tube heater must be connected and tested in accordance with national, state,
and local codes along with guidelines in this manual. In the United States refer to the latest edition
of the ANSI Z223.1 (NFPA 54) Standard and in Canada refer to the latest edition of the CAN/CGA
B149.1 Standard.
Supply gas piping to the unit should conform with the local and national requirements for type and
volume of gas handled, and pressure drop allowed in the line. Avoid pipe sizes smaller than 1/2”.
The installation must conform with local building codes or, in the absence of such codes, the National
Fuel Code (NFPA 54) and in conjunction with ANSI Z21.24/CSA 6.10 “Connectors for Gas Appliances”.
NOTICE
The total input to the appliance must fall /- 5% of the rated input as indicated on the rating
plate. Otherwise the heat exchanger may prematurely fail.
IMPORTANT!
The heating system will expand and contract during operation.
Allowances for
expansion must be made between the connection to the heater and the gas supply.
A flexible gas
connection of approved type is required. Flexible stainless steel gas connectors installed in one plane,
and without sharp bends, kinks, or twists is recommended.
