9.0) TYPICAL SUSPENSION METHODS
Burner must be secured to the mounting flange with nuts.
All materials used to suspend the heater must have a minimum working load
of 115 lbs.
All S Hooks must be crimped closed.
Never use the heater to support a ladder or other access equipment.
Failure to do so may result in death, serious injury or property damage.
SUSPENSION HAZARD
Variou mean of u pending the heater can be u ed. See the following drawing for typical example .
1. U e only noncombu tible material for u pending hanger and bracket .
2. A minimum No. 2 chain with a working load limit of 115 lb . i required.
3. Turnbuckle can be u ed with chain to allow leveling of the heater. All “S” hook and eye bolt mu t be
manually crimped clo ed by the in taller.
4. When u ing rigid mean for heater u pen ion (rod, flat bar, etc.) provide ufficient length or wing joint to
compen ate for expan ion. See Figure b and c.
5. Heater ubject to vibration mu t be provided with vibration i olating hanger .
6. Heater mu t not be upported by ga or electric upply line and mu t be u pended from a permanent
tructure with adequate load capacity.
Me tek recommend that the tube ection be u pended u ing chain with turnbuckle . Thi will allow light
adju tment after a embly and heater expan ion/ contraction during operation.
If a “trapeze” method i u ed for tube upport/hanger bracket ( hown below), the minimum chain length for the
two connecting chain i 36” to minimize any vibration that might be generated by the draft inducer a embly. If
the e chain mu t be le than 36”, then do not u e the trapeze method and, in tead, u e individual chain on
each tube upport/hanger bracket.

11.0) GAS CONNECTIONS AND REGULATIONS
Tighten flexible gas hose and components securely.
Flexible metal gas hoses must be installed without any twists or
kinks in them. The hose will move during operation of the heater
and it can crack if it is twisted.
Failure to do so may result in death, serious injury or property
damage.
IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER

IMPORTANT BEFORE CONNECTING THE GAS TO THE HEATER
1. Connect to the upply tank or manifold in accordance with the late t edition of National Fuel Ga Code (ANSI
Z223.1), and local building code . Authoritie having juri diction hould be con ulted before the in tallation

In tallation Code.)
2. Check that the ga fuel on the burner rating plate matche the fuel for the application.
3. Check that the ga upply piping ha the capacity for the total ga con umption of the heater and any other
equipment connected to the line.
4. Check that the calculated upply pre ure with all ga appliance and heater operating will not drop below
the minimum upply pre ure required for the e heater . Check inlet upply pre ure on Section 12.0).
5. All ga upply line mu t be located in accordance with the required clearance to combu tible from the
heater a li ted on the clearance label of the heater and Section 4.0) of thi manual.
6. Pipe joint compound mu t be re i tant to the action of liquefied petroleum ga e .
7. Tube heater will expand/contract during operation. Where local code do not prohibit, a CSA or U.L.
approved flexible connector upplied with thi heater i required for connection between the rigid piping
and the heater. A union hould be in talled before the control box inlet. An approved hut off valve hould be
in talled within 6 feet of the union.
