11.Installing Heater and Louvers (cont’d)

Installing Louvers

NOTE: Do not install louvers if installing a nozzle. Follow the instructions shipped with the nozzle.

FIGURE 6 - Use Compression Springs to Install Louvers in the Discharge Opening(s)

CAUTION: To avoid getting burned, adjust louvers while heater is not operating. If adjusting louvers while heater is operating, wear gloves.

After the unit is suspended/mounted, install the air directional louvers or optional nozzle. If an optional nozzle is being installed, follow the instructions included with the nozzle. If a nozzle is not being used, install the louvers in the discharge opening(s). Louvers and springs are in the hardware kit shipped with the heater.

Before actually installing the louvers, note the louver curve and determine how the louvers should be positioned to provide the optimal throw pattern. Opening is square so louvers may be installed either horizontal or vertical. Louvers may be installed with the curve all the same direction (either way) or the right half one way and left the other as illustrated in FIGURE 6.

Louver Installation Instructions:

1)With the wider section of the louver facing out of the heater, place one of the compres- sion springs over the tab on the notched end of a louver. The end of the louver with the spring will fit in any direction in the square opening. How the louver turns depends on which end of the louver is inserted first.

2)Depending on the throw pattern selected, push the louver tab with the spring into a hole in the discharge opening and insert the louver tab on the other end into the corresponding hole on the opposite side.

3) Continue until all louvers are installed. Adjust the louvers to provide the

desired throw pattern.

12.Gas Piping and Pressures

WARNING: This appliance is equipped for a maximum gas supply pressure of 1/2 psi, 3.5 kPa, or 14 inches water column. Supply pressure greater than 1/2 psi requires installation of an additional lockup-type service regulator external to the heater.

WARNING: PRESSURE TESTING SUPPLY PIPING

Test Pressures Above 1/2 PSI: Disconnect the heater and manual valve from the gas supply line which is to be tested. Cap or plug the supply line.

Test Pressures Below 1/2 PSI: Before testing, close the manual valve on the heater.
