PART 3: PREPARE MUNCHKIN CONTENDER LOCATION
(CONTINUED)
BEFORE LOCATING THE MUNCHKIN
CONTENDER
1. Check for nearby connection to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
2. Check area around heater. Remove any
combustible materials, gasoline and other
flammable liquids.
3. The Munchkin Contender must be installed
so that gas control system components are
protected from dripping or spraying water or
rain during operation or service.
4. If the new Munchkin Contender is to replace
an existing heater, check for and correct any
existing system problems such as:
• System leaks.
• Incorrectly-sized expansion tank.
• Lack of freeze protection in heating water
causing system and heater to freeze and
leak.
• Excessive glycol which will affect the
heater system operation.
C. CLEARANCES FOR SERVICE ACCESS
1. See Figure 3-1 for recommended service
clearances. If you do not provide minimum
clearances shown, it might not be possible to
service the heater without removing it from
the space.
WARNING
Failure to keep heater area clear and free of
combustible materials, gasoline and other
flammable liquids and vapors can result in
severe personal injury, death or substantial
property damage.
