1.GENERAL INFORMATION

a.Your heater comes fully assembled and is tested at the factory for proper gas and input as stated on the name plate.

b.Before proceeding with the installation, be sure to inspect for damages. Freight company must be noti- fied of any damages and request that an inspection be made by the freight company. HEAT STAR will send replacement parts for damaged parts only after receiv- ing a signed inspection report to prove the liability of the freight company.

c.Do not attempt to operate heater with any other gas than that indicated on the heater name plate.

d.The installation of heater must conform with local building codes or, in absence of local codes, with the National Fuel Gas Code, ANSI Z223.1a/NFPA54. In Canada, refer to Can 1-B146.1 and B149.2.

e.Plugged 1/8” N.P.T. Test Gage Connection is located on the Heater Gas Control or a ¼” N.P.T. Connection is located on the outside of the Cast Venturi.

2.CLEARANCES Minimum clearances to combustibles. (Refer to Figure 1)

Provide adequate clearance to combustibles, Figure 1, between control end of heater for servicing and mini- mum on top and sides for ventilation and combustion air supply.

A minimum clearance of 8’ above floor for public garages in accordance with ANSI/NFPA No. 88 most re- cent edition or Figure 1; whichever is larger. In Canada refer to Can 1-B149.1 and B149.2 Installation codes for Gas burning appliances.

A minimum clearance of 10’ from the bottom of heater to top of wing, or engine enclosure, where aircraft are housed, and 8’ above floor in other areas of the hang- er in accordance with ANSI/NFPA No. 409 most recent

Figure 1

edition, or Figure 1; the larger dimension of ANSI/NFPA No. 409 or Figure 1 is to be used. In Canada refer to CCA B149-1-M91 and B149.2.

WARNING: Maintain clearances as shown in Figure 1 or on heater nameplate, in garage installations where parked vehicles are di- rectly below the heater.

3. SUSPENSION

Heater has four mounting holes, two on each end, for attaching rod or angle iron brackets and shall be safely and adequately fixed in position independent of gas and electric supply lines. Refer to Figures 4, 5, and 7 on pages 13 and 14 for recommended suspensions.

4. GAS SUPPLY

Provide adequate gas supply for rated input of each heater using American Standard Installation of gas piping and gas appliances in building ANSI/223. 1a/ NFPA54 Pamphlet, Table C-3 shows capacity of pipe of different diameters and lengths in cubic feet per hour for Natural Gas with pressure drop of 0.3 inches specify gravity of 0.60. For liquefied Petroleum Gas (LP) capac- ity refer to Table C-3 and C-15 of the same pamphlet. For recommended heater gas connection refer to Figure No. 5, Page 15. In Canada refer to Can 1-B149.1 and B149.2, and CSA sto. B63.

If gas lines are to be pressure tested with compressed air, disconnect each heater to prevent control damage and cap outlets. After reconnecting all heaters, purge gas lines of air and check all connections for leaks us- ing soap solution.

WARNING: Do NOT USE MATCH OR OTHER FLAME FOR LEAK TESTING.

5. GAS PRESSURE

When a higher than the maximum recommended gas pressure is being maintained at the main gas line,
