HEATER SERVICING POSITION:
WHEN USING WALL MOUNT BRACKET JP-2300-MB (see Figure 4 next page), the heater
may need to be rotated ‘up’ so that access is provided to the service access door at the rear
side of the heater that is against the wall.
1. To allow rotation of the heater, slacken the upper bolt fastening the heater bracket to the
wall mounting bracket .
2. Remove the lower bolt securing the two brackets and rotate the heater up to the service
position.
3. Insert the bolt in the upper bracket hole to hold the heater for servicing, and apply locking
nut to bolt for extra safety. Heater panel can now be accessed and serviced safely.
4. NOTE: Do not start up the heater when in this upper service position as the gas
valve is in a compromised position. Before starting the heater, ALWAYS restore the
heater bracket back to its original plane and correct support position.
5. To restore the heater to the operating position, lift and support the weight of the heater and
remove nut and bolt from upper hole.
6. Slowly rotate the heater back down to the correct operating position.
7. Insert and fasten the bolt in the bottom hole, and secure with the nut.
8. At completion of service, ensure that both bracket support bolts are tightened securely.
Servicing of heater is essential for continued efficient operation. Servicing should be carried
out annually by a qualified gas service technician as follows:
 Clean the ceramic tiles with compressed air. Avoid directing air stream at gasket material
between tile and heater body. The air pressure must be lower than 20 psig.
 Clean venturi tube with compressed air. The air pressure must be lower than 20 psig.
 Ensure gas orifice is clean and the heater cabinet is free of any debris
