III Before Installing
1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict
accordance with this manual and the authority having jurisdiction.
• In the absence of an authority having jurisdiction, installation must be in accordance with this manual and
the National Fuel Gas Code, ANSI Z223.1.
• Where required by the authority having jurisdiction, this installation must conform to the Standard for
Controls and Safety Devices for Automatically Fired Boilers (ANSI/ASME CSD-1).
2) CHG boilers utilize aluminum heat exchangers constructed, tested, and stamped in accordance with ASME
Boiler and Pressure Vessel Code Case 2382-2. Some jurisdictions which require ASME boiler construction
do not recognize this Code Case and may not approve the installation of an aluminum boiler. Consult the
authority having jurisdiction before installing this boiler.
3) Read Section VI to verify that the maximum combustion air and exhaust pipe lengths will not be exceeded in
the planned installation. Also verify that the vent terminal is installed in the proper location.
4) Make sure that the boiler is correctly sized:
• For heating systems employing convection radiation (baseboard or radiators), use an industry accepted
sizing method such as the I=B=R Heat Loss Calculation Guide (Pub. #H21 or #H22) published by the
Hydronics Institute in Berkeley Heights, NJ.
• For new radiant heating systems, refer to the radiant tubing manufacturer’s boiler sizing guidelines.
• For systems including an Alliance™ indirect water heater, size the boiler to have either the DOE Heating
Capacity required for the Alliance™ or the net rating required for the heating system, whichever results in
the larger boiler.
• For systems that incorporate other indirect water heaters, refer to the indirect water heater manufacturer’s
instructions for boiler output requirements.
5) Make sure that the boiler received is configured for the correct gas (natural or LP).
6) Make sure that the boiler is configured for use at the altitude at which it is to be installed.
IV Locating the Boiler
1) Observe the minimum clearances shown in Figure 4.1. These clearances apply to both combustible and non-
combustible materials. Observe the minimum clearances to combustibles for vent pipe shown in Table 4.2.
2) Note the recommended service clearances in Figure 4.1. The recommended service clearances may be
reduced to the minimum combustible clearances with the understanding that servicing the boiler will become
increasingly difficult as the clearance is reduced.
3) Boiler may be installed on non-carpeted combustible surface.
4) The relief valve must be installed in the factory specified location.
5) The boiler should be located so as to minimize the length of the vent system.
6) The combustion air piping must terminate where outdoor air is available for combustion and away from areas
that will contaminate combustion air. Avoid areas near chemical products containing chlorine, chloride based
salts, chloro/fluorocarbons, paint removers, cleaning solvents and detergents.
