Installation, Operating & Service Manual

1 Product Description

This is a cast iron gas-fired boiler designed for use in forced hot water heating systems. It is intended for instal-

lations where a usable chimney is not available. This boiler is vented using an approved vertical or horizontal

AL29-4C stainless steel venting system, which is not included with the boiler. This boiler requires an adequate

source of clean combustion air in the boiler room. Alternatively, combustion air may be piped directly from the

outdoors to the boiler using an optional Direct Vent Conversion Kit shown in Table 2.2.

This boiler is not designed for use in gravity or “open” heating systems.
