INSTALLATION (1 OF 2)
CAUTION
•
DO NOT use gas piping or electrical conduit to provide any type of support for the heater’s suspension.
•
Means of suspension MUST BE able to support twice the weight of the heater, securely fastened to the building’s
structure, and allow for expansion during its operation.
•
Chain for suspension MUST BE 12 in. (31cm) minimum in length and be 1/0 TENSO with a minimum working load rating
of 200 lbs. (90.7 kg).
•
The “S” hook MUST BE Chicago Hardware no. 5 or equal and carry a 70 pound (32kg) maximum load.
STEP
1
•
Use a taut string in the planning of suspension points to maintain straightness over the length of the system.
Make true right angles if elbows are used.
•
Check the BASIC SYSTEM CONFIGURATIONS section for the general orientation of components matching
the model number of your system.
•
Identify all components in the COMBUSTION CHAMBERS and HEAT EXCHANGERS sections.
•
U-type systems use a 180-degree U-bend. See U-TUBE INSTALLATION section.
STEP
2
•
Install chain for suspension of tubes and reflectors.
•
The suspension points for each 10-foot (3.0m) tube should be a
minimum of 4 feet (1.2m) and a maximum of 8 feet (2.4m) apart.
•
Use a minimum of 12 in. (31cm) of chain for each suspension point.
•
Install a chain to be positioned at the joint between the combustion
chamber and the burner.
•
Install an additional suspension point, for a required safety chain at
the back of the burner box 17.5 in. (44cm) from the joint between the
combustion chamber and the burner. The burner safety chain should
have an additional 6 in. (15cm) of length added to allow for slack.
•
Install tube/reflector hangers. Slip one end of the S-hook through the
last chain link and the other end through the tube/reflector hanger.
•
IMPORTANT: Crimp both ends of the S-hook closed!
STEP
3
•
Identify all components in COMBUSTION CHAMBERS
and HEAT EXCHANGERS sections of this manual.
•
Check the BASIC SYSTEM CONFIGURATIONS section
of this manual for the general orientation of components
matching the model number of your system.
•
Systems fifteen (15) feet (4.6m) or longer require joining
together of combustion chamber and heat exchanger
tube(s). See TUBE ASSEMBLY TIPS section.
•
For U-type systems, a 180-degree u-bend is also used.
See U-TUBE INSTALLATION section.
•
Slip the burner coupling over the end of the combustion
chamber marked “BURNER END”.
•
Rotate the burner coupling until the two holes on one end
of the coupling are each 90 degrees apart from the weld
seam on the combustion chamber and seat it against the
center stop.
•
Use (2) #12 MULTI-METAL Tek screws (supplied with the
coupling) to fasten the coupling to the combustion
chamber.
•
Tubes MUST NOT be dragged along the ground or other
surfaces which may damage the ends.
STEP
4
•
Take this assembly, with the weld seam still facing up, and place the end marked “BURNER END” into the
first two suspended hanger bracket assemblies at the point where the burner will eventually be located.
•
Place a reflector (gloves are suggested; handle the reflectors with care as not to soil the shiny underside) over
the combustion chamber and into the suspended hanger bracket assemblies.
CAUTION: MB SERIES
•
All burner covers are yellow, except for the MB Series, which are white. The MB burner must be used with an GQH9
heat exchanger, which has a piece of white tape at the exhaust end (NO EXCEPTIONS). Improper operation may
result if this is not followed.
