U Horizontal Recommended Minimum 14 ft 12ft 16ft 14ft 18ft 16ft Inclined Recommended Minimum 11ft 10ft 13ft 12ft 15ft 14ft Ensure that there is adequate provision in the building for combustion and ventilating air supply. Installation must meet minimum requirements of applicable codes. When installed in public garages and airplane hangars ensure that minimum clearances specified in ANSI/NFPA 88A or B, ANSI/NFPA 409, respectively, are met; and in no case less than those in the preceding tables. A.4 PRE-ASSEMBLY Each heating unit is assembled as follows: Note that the emitter tube consists of more than one tube. The tube to be connected to the burner box is the thinner stainless steel or aluminized steel tube. Other tubes may be mild (thicker tubes), stainless or aluminized steel. Connections between tubes is by a coupling with three bolts. The coupling has an inner compression sleeve that holds the pipe securely when the nuts are turned tight. Support the assembled radiant tube with screws facing upwards, on blocks, etc. at least 6” above floor level, preferably under the position of installation. Ensure that the tube is clear internally. Slip the suspension brackets onto the tube assembly and attach by means of “U” bolts and nuts. Note that there are two types of brackets; type C and type B. Type C attaches reflectors together. Bracket C & B are placed on the assembled radiant tube in position shown on the assembly drawing in APPENDIX “A”. Tighten nuts to secure brackets to the tubes at spacing indicated with all brackets oriented in the same level position. NOTE: CLOSE ALL S-HOOKS TO INSURE THAT THE CHAINS DO NOT COME OFF OF THE HOOK. 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -6 A.5 INSTALLATION Heater units: At this point raise the tube assembly into position and suspend from previously fixed chains (9 gauge min. galvanized welded link construction), or attach to wall mounting brackets. Wall mounting brackets must support heater at an angle of inclination of 45° ±10°. Longer tube assembly may be raised in more than one sub-assembly with final tube connection made in the air. It is recommended that the heater be suspended to slope slightly downward from the burner approximately 1 inch in 20 feet, but not more than 2-inches total. Remove the protective plastic film from the reflector surface. Note that each section of reflector has two holes punched at one end. This end is firmly fixed by bolting to the lugs provided on the reflector bracket type C. The other end of each reflector section is free floating in suspension bracket type B thereby allowing for thermal expansion. Position reflector sections so that ends with holes lap at type C brackets and secure with nuts, bolts, and large washers provided in the burner box crate. Reflector should be allowed free movement through brackets type B. Note: Reflectors may be installed before tube is raised to position at installer’s option. Slide burner/control assembly onto the burner end of the radiant tube ensuring it is fully engaged and upright, (i.e. with air inlet cover plate facing upwards) and secure with locking screws provided. Slide the fan assembly on the opposite end of radiant tube, ensuring that it is fully engaged with fan outlet facing horizontally for outdoor installations and for indoor installations either unvented or with horizontal thru wall venting. Fan outlet should face upward for vertical venting thru the roof. 2319 Laurelbrook Street, Raleigh, NC 27604 · (800) 542-7221 · FAX (919) 834-4526 · -7 A.6 GAS CONNECTION The gas connection on the heater is .” NPT external thread. SERVICE REQUIREMENTS NAT. GAS L.P. GAS Max. inlet gas supply pressure (in.w.c.) Min. inlet gas supply pressure (in.w.c.) 10.0 6.5 14.0 11.0 Injector sizes and manifold pressure for the burner are shown in the attached table for all heater units. The gas supply piping and connections must be installed so that the minimum pressure stated is achieved. A gas shut-off valve and union should be fitted in the gas supply line close to the heater, and a 1/8 inch N.P.T. plugged tapping, accessible for test gauge connection, provided immediately upstream of the appliance gas inlet. It is essential to provide some flexibility in the final gas connection preferably by use of an approved armored flexible connector or stainless steel expansion loop.
