At that 12.5 MBH mark, a new standard applies — NFPA 85, Boiler and Combustion Systems Hazard Code. In my experience, these are the things the authority having jurisdiction looks for immediately.

Read MoreThe PVG Power Venter is used for side wall venting of a single 24 VAC controlled furnace, boiler, or water heater which burns natural or LP gas. The PVG may also be used to vent a single 24 VAC controlled gas fired furnace or boiler and a 30 millivolt residential gas fired water heater. The indoor mounted PVG Power Venters provide a safe
Read MoreMar 27, 2012 · I usually use a boiler bypass on large cast iron systems if not piped p/s. Piped p/s we can just reduce the flow through the boiler. When considering boiler condensation we need to worry more about the volume of cool water more than the temperature. Less water volume in boilers means slow down the flow to mix in the boiler.

Read MoreA low-water fuel cutoff is used on both steam and hot water boilers to shut off the fuel or source of heat when the water drops below a predetermined, safe operating level. The most common type of low water fuel cutoff is a float inside a chamber. The float mechanism actuates an electrical switch when the float reaches a preset level.
Read MoreThe heating controller is a weather-compensated controller for sliding boiler operation. It is micro-processor controlled with menu-controlled easy operation via rotary/pressing element and supplied with a large-sized, backlit LC display. The controller is provided with a 3-point output with circulation pump logic and boiler restart relief. The …
