Recommended Boiler Piping

e.A hot water boiler installed above radiation level must be provided with a low water cutoff device as part of the installation.

If a low water cut-off is required, it must be mounted in the system piping above the boiler. The minimum safe water level of a hot water boiler is just above the highest water containing cavity of the boiler; that is, a hot water boiler must be full of water to operate safely.

f.Use a boiler bypass if the boiler is to be operated in a system which has a large volume or excessive radiation where low boiler water temperature may be encountered (i.e., converted gravity circulation system, etc.). The bypass should be the same size as the supply and return lines with valves located in the by-pass and supply outlet as illustrated in order to regulate water ﬂow for maintenance of higher boiler water temperatures. See Figure 6.

Set the by-pass and boiler supply valves to a half throttle position to start. Operate boiler until the system water temperature is at a normal operating range.

Adjust the valves to provide 180° to 200°F supply water temperature. Opening the boiler supply valve will raise the system temperature, while opening the by-pass valve will lower the system supply temperature.

If it is required to perform a long term pressure test of the hydronic system, the boiler should ﬁrst be isolated to avoid a pressure loss due to the escape of air trapped in the boiler.

To perform a long term pressure test including the boiler, ALL trapped air must ﬁrst be removed from the boiler.

A loss of pressure during such a test, with no visible water leakage, is an indication that the boiler contained trapped air.

7INSTALL BOILER FLUSH JACKET (See Figure 9).

a.Open jacket carton and locate side panels. Note that jacket left side panel is not insulated and right side panel is insulated.

b.Position the rear ﬂange on jacket left side panel behind the boiler back plate. Position ﬂange support notches over jacket support hooks on back panel and engage jacket on both support hooks to keep the panel from moving front to rear.

c.Position rear ﬂange on jacket right side panel behind upper and lower jacket support brackets. Engage jacket with jacket support hooks in similar manner as left side panel to provide proper positioning and support.

d.Take jacket top and bottom panel from carton. Top panel can be identiﬁed by the front channel used to
