environments, boilers must not be installed using direct vent systems which draw outdoor air for combustion. Such boilers must be
installed using room air for combustion. Indoor air will have a much lower relative humidity and, hence, potential corrosion will be
minimized.
This boiler is certified for indoor installations only. Do not install the boiler outdoors. Failure to install this boiler indoors could result in
substantial property damage, severe personal injury, or death.
2. Check for nearby connections to:
System water piping
Venting connections
Gas supply piping
Electrical power
Condensate drain
3. Check area around boiler. Remove any combustible materials, gasoline, and other flammable liquids.
Failure to keep boiler area clear and free of combustible materials, liquids, and vapors can result in substantial property damage,
severe personal injury, or death.
4. Gas control system components must be protected from dripping water during operation and service.
5. If the boiler is to replace an existing boiler, check for and correct any existing system problems, such as:
System leaks
Location that could cause the system and boiler to freeze and leak.
Incorrectly-sized expansion tank
6. Clean and flush system when reinstalling a boiler.
NOTE:
When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to
make note of the boiler model and serial number.
Gas conversion should be performed BEFORE the boiler is installed. Carefully follow the gas conversion instructions when performing
the conversion. Failure to do so could result in property damage, severe personal injury, or death.
Consider boiler piping and installation when determining boiler location.
B. LEVELING
In order for the condensate to properly flow out of the collection system, the boiler must be installed level. The location must also
support the boiler when it is full of water.
C. CLEARANCES FOR SERVICE ACCESS
See Figure 1 for recommended service clearances. If you do not provide the minimum clearances shown, it may not be possible to
service the boiler without removing it from the space.
