Page 6: Installation
Do not install unit heaters in corrosive or fl ammable atmospheres! Premature failure of, or severe damage to the unit will result! Avoid locations where extreme drafts can affect burner operation. Unit heaters must not be installed in locations where air for combustion would contain chlorinated, halogenated or acidic vapors. -
Page 7: Installation Codes
The Unit Heater may be mounted by fastening the hanging brackets directly to ceiling joists or by suspending from four rods. See Figures 3, 4 and 5. Make certain that the lifting methods used to lift the heater and the method of suspen- sion used in the fi... -
Page 8: Pipe Sizing
To avoid damage or possible personal injury, do not connect gas piping to this unit until a supply line pressure/leak test has been completed. Connecting the unit before completing the pressure/leak test may damage the unit gas valve and result in a fi re hazard. Do not rely on a shut-off valve to isolate the unit while conducting gas pressure/leak tests. -
Page 9: Pipe Installation
1. Install the gas piping in accordance with applicable local codes. 2. Check gas supply pressure. Each unit heater must be connected to a gas supply capable of supplying its full rated capacity as specifi ed in Table 3. A fi eld LP tank regulator must be used to limit the supply pressure to a maximum of 14 in. -
