Remove the electrical panel and the cover of the electrical panel as indicated in Figure 22, taking care not to tear the cables.
-
Remove the cables of the electrode from the PIN of the control board. After this operation, remove the electrode by removing the 2 fixing screws. See Figure 23.
WARNING: At the end of any maintenance procedure, testing gas piping using only a soap and a water solution. Do not use a match or other flame for leak testing. If during leakage check gas is smelled, turn off the gas supply and ventilate the building.
MAINTENANCE INTERVALS
Frequency of operation and operating conditions will determine how often to
perform maintenance checks on the heater:
Intermittent use: Appliances that are used seasonally should be checked before
shutdown and again before the next use.
Dusty, wet or corrosive environment: Since these environments can cause the
gas control to deteriorate more rapidly, the system should be checked more
often.
NOTICE: The gas control should be replaced if it does not perform
properly on start-up or trouble shooting.
FUEL CONVERSION INSTRUCTIONS
**WARNING:** Before doing all the operations below, it is necessary to close the manual main shut-off gas valve and to remove plug from the socket.
- Remove the top cover and the side cover (from valve side). Refer to Figure 18.
- Remove the gas connection from the gas valve.
- Remove the 3 screws securing the air flange and remove the gas valve connector. Refer to Figure 20. To remove the screws use the “10 key”.
- Once the valve assembly has been removed, replace the NG nozzle with the propane nozzle using a “13 key”. See Figures 25 and 24. The nozzle is supplied by Heat Star. Verify the orifice drill size in Table 1.
- Reassemble the unit by performing Steps 1-3 in reverse order.
- Make the gas connection as indicated in the GAS SUPPLY INSTALLATION INSTRUCTIONS section.
- At the first re-ignition with different gas, adjust the manifold pressure to the pressure indicated in Table 1 and on the label applied on the unit. See Figure 13 for valve adjustment.
- Replace the NG label with data of manifold pressure and orifice drill size with the propane label (supplied with the unit).
