Oxygen Corrosion | Burnham SM-6 guide

b.Drill four (4) pilot holes, properly sized for the non-corrosive fasteners (stainless steel, brass or aluminum) to be used to secure the wall ﬂange to wall.

c.Attach four (4) ½” long threaded aluminum spacers to the outer ﬂanges of the exterior telescoping intake air duct wall ﬂange with four (4) #10-32 x ¼” long stainless steel machine screws provided. (See Figure 5).

d.Apply a ¼” thick continuous bead of silicone rubber type caulking to the rear of the exterior telescoping intake air duct wall ﬂange approximately 1” from duct.

e.Re-install exterior telescoping intake air duct and secure to wall.

NOTE: Non-corrosive (stainless steel, brass or aluminum) fasteners must be used.

f.Apply a bead of silicone rubber caulking to perimeter of wall ﬂange, where the wall and ﬂange join. Use a tool or your ﬁnger and apply pressure while smoothing caulking to provide a weather-tight seal.

4INSTALLING VENT TUBE, ORIFICE PLATE AND VENT TERMINAL COVER (See Figures 4 and 5).

a.The vent tube furnished has a standard length of 24”. This length is suitable for a wall thickness from 5” to 15”.

b.To determine the proper length required, place a 24” level horizontally across the exterior wall ﬂange, just below the aluminum spacers, measure the distance between the outlet ﬂange on the fan and the level. Add 1” to this measurement for the total length of the vent tube.

c.Measuring from the ﬂange end of the vent tube, mark the total length required. Cut off and discard the remaining piece.

d.IMPORTANT! Before connecting vent tube to fan, install the oriﬁce plate and two (2) ceraﬁbre gaskets on the fan outlet ﬂange weld studs in the proper order of assembly, gasket ﬁrst, oriﬁce plate second and remaining gasket last. (See Figures 4 and 5).

e.Insert the vent tube, ﬂange ﬁrst, through the intake air duct and secure to fan outlet ﬂange with four (4) ¼” ﬂat washers, ¼” lock washers and ¼”-20 brass hex nuts provided.

f.Position vent terminal cover over exterior intake air duct. Insert end of vent tube into collar on rear of vent terminal cover. Align four (4) holes on cover with ½” long threaded aluminum spacers. Secure vent terminal cover with four (4) #10-32 x ¼” long stainless steel machine screws provided.

5DO NOT REPLACE ENCLOSURE COVER until boiler piping is completed and system is ﬁlled, vented and checked for water leaks.

6CONNECT SUPPLY AND RETURN PIPING TO heating system.

OXYGEN CORROSION:

Oxygen contamination of the boiler water will cause corrosion of the iron and steel boiler components, which can lead to failure. As such, any system must be designed to prevent oxygen absorption in the ﬁrst place or prevent it from reaching the boiler. Problems caused by oxygen contamination of boiler water are not covered by Burnham’s standard warranty.

There are many possible causes of oxygen contamination such as:

1.Addition of excessive make-up water as a result of system leaks.

2.Absorption through open tanks and ﬁttings.

3.Oxygen permeable materials in the distribution system.

In order to insure long product life, oxygen sources should be eliminated. This can be accomplished by taking the following measures:

1.Repairing system leaks to eliminate the need for addition of make-up water.

2.Eliminating open tanks from the system.

3.Eliminating and/or repairing ﬁttings which allow oxygen absorption.

4.Use of non-permeable materials in the distribution system.

5.Isolating the boiler from the system water by installing a heat exchanger.

a.For heating only, see Figure 6. Consult I=B=R Installation Guides. Clearance between hot water pipes and combustible material must not be less than ½”.

b.If this boiler is used in connection with refrigeration systems, the boiler must be installed so that the chilled medium is piped parallel with the heating boiler using appropriate valves to prevent the chilled medium from entering the boiler, see Figure 7. Also consult I=B=R Installation and Piping Guides. If this boiler

is connected to heating coils located in air handling units where they may be exposed to refrigerated air, the boiler piping must be equipped with ﬂow control valves to prevent gravity circulation of boiler water during the operation of the cooling system.

c.Pipe safety relief valve to suitable drain.

CAUTION: Safety relief valve should be piped to an open drain — full size of discharge outlet on relief valve without any provision of “shut-off” between the relief valve and discharge into drain.

d.Install diaphragm type expansion tank (not furnished) in system piping.

SM-6 specifications

The Burnham SM-6 is a high-performance modular boiler designed for commercial and industrial applications. Known for its efficiency and reliability, the SM-6 is engineered to meet a wide range of heating demands while maintaining low operational costs.
