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 requirements of 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-latest edition.
•
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)-latest edition.
2) Make sure that a properly sized chimney is available which is in good condition. Consult the authority having
jurisdiction, Part VI of this manual, and the
National Fuel Gas Code
for additional information on venting requirements.
3) Make sure that the boiler is correctly sized. Use an industry accepted sizing method such as the
I=B=R Installation
Guide for Residential Hydronic Heating Systems (Pub. #200) and I=B=R Heat Loss Calculation Guide
(Pub. #H21 or #H22)
published by the Hydronics Institute in Berkeley Heights NJ.
4) Make sure that the boiler received is configured for the correct gas (natural or LP). The CWI311, CWI346 and CWI380
may only be used with natural gas.
5) Boilers installed at altitudes above 2000 ft. may require different burners and main burner orifice than those at sea level.
Make sure that the boiler is configured for use at the correct altitude.
6) If this boiler was received as a knockdown boiler, follow the instructions in Appendix A to assemble the boiler.
IV Locating the Boiler
1) Clearances:
•
Observe the minimum clearances shown below. These clearances apply to all combustible construction, as well as
noncombustible walls, ceilings and doors. Also see Figure 2.

Top – 17”
•
A 24” service clearance from the jacket is recommended on the left, right, and front of the boiler. These clearances
may be reduced to those shown in Figure 2, however servicing the boiler will become increasingly difficult as these
service clearances are reduced.
