Burnham E4 manual Section I Installation Instructions

SECTION I: INSTALLATION INSTRUCTIONS

A.Inspect Shipment carefully for any signs of damage.

1.All equipment is carefully manufactured, inspected and packed. Our responsibility ceases upon delivery of Boiler to the carrier in good condition.

2.Any claims for damage or shortage in shipment must be filed immediately against the carrier by the consignee. No claims for variances from, or shortage in orders, will be allowed by Boiler Manufacturer, unless presented within sixty (60) days after receipt of goods.

B.Read These Instructions Carefully before proceeding with installation and operation of the “CARE-FREE” Electric Boiler.

1.The “CARE-FREE” is U.L. listed, constructed and tested in accordance with the requirements of the ASME Boiler and Pressure Vessel Code and designed for use in any conventional hydronic system except steam and gravity hot water.

2.The “CARE-FREE” Electric Boilers are shipped completely assembled less circulator. All electrical controls are mounted and wired in a compartment immediately behind the Front Door of the Boiler Jacket, see Figure 1.

C.Locate Boiler in or adjacent to the space to be heated with consideration given to the location of the electrical service. Although its compactness will allow the “CARE-FREE” Electric Boiler to be mounted almost anywhere – closet, alcove, or other small area, see CLEARANCE REQUIREMENTS on Page 2.

D.Mount Boiler to wall using four 3/8" lag screws or anchor bolts (depending upon wall construction)

passing through the holes provided in the wall mounting channels. Figure 1 shows bolt center dimensions. It is recommended that 1/2" plywood be used as a base for mounting the boiler so that the structure is adequate to carry the weight imposed upon it – see Figure 1 for weight of boiler when full of water. Boiler should be level for proper operation of BUILT-

IN AIR SEPARATOR.

E.Connect Supply and Return Piping to Heating System using standard recognized practices. See Figure 2. Install an appropriate size expansion tank in system as per Figure 2. Do not connect into the 3/4" tee on top of the boiler; instead install an automatic float type air vent at this point. Water content of the boiler is given in Figure 1.

The relief valve outlet should be piped full size to a drain or near the floor.

The heating elements are NOT compatible with ethylene glycol based antifreeze.

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.

If it is required to perform a long term pressure test of the hydronic system, the boiler should first e isolated to avoid a 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.
