2 EH-M2-40 Boiler Operation and Installation Instructions
DESCRIPTION
The Monitron II boiler is a low pressure hot water heating electric
boiler. The control is a 4 stage electronic control with energy
saving and other features. The heating elements are sheathed
resistance type. The heat exchanger is cast-iron. The heat
exchanger is constructed, inspected, and stamped in accordance
with Section IV of the American Society of Mechanical Engineers
(ASME) Boiler and Pressure Vessel Code. In addition, the
Monitron II Boiler is equipped with a safety relief valve conforming
to ASME requirements and two separate limit controls conforming
to U.L. requirements. The Monitron II boiler is Underwriters'
Laboratories, Inc. listed.
MOUNTING THE BOILER ON A WALL
Be sure that the wall is vertically plumb and capable of carrying the
weight of the boiler and the system piping, when full of water. The
boiler full of water is approximately 45kg (100 lbs). Add to this the
weight of the system piping that the boiler will be supporting.
Be sure that there are studs available in the proper locations, for
securing the boiler wall bracket and back panel.
(See Figures 1 and 1a).
For wood stud walls, use lag screws or wood screws with a coarse
thread and a minimum of 76mm (3”) in length.
For metal stud walls, use toggle-style bolts that are specifically
designed for such and maximum capacity exceeds the weight of the
boiler and the system piping when full of water.
DO NOT use anchors driven into sheetrock to hold the boiler up on
the wall. If mounting the boiler on a cement wall, use anchors that
are specifically designed for such, and maximum capacity exceeds
the weight of the boiler and the system piping, when full of water.
A. INSTALL THE WALL BRACKET. SEE FIGURE 1A.
1. Remove the wall bracket from the wood packing, by unfastening
the two screws that holds it in place, for shipping purposes only.
2. Select the location on the wall where the boiler will be mounted.
The upward facing tabs of the wall bracket will align with the top
surface of the boiler jacket.
3. For sheetrock and stud construction, locate the studs and
determine which set of holes in the wall bracket best align
with the center of the studs. For cement walls, determine a
location for the wall bracket to mount where the anchors will
be secure, devoid of seams or cracks.
4. Place the bracket in the selected location, with the 2 tabs
positioned up and facing outward, level it out, and mark the
holes to be used. A minimum of 4 of these holes must be
utilized, regardless of wall material.
5. Drill the appropriate diameter and depth holes for the
fasteners used in the wall, where marked.
6. Fasten the wall bracket to the wall, being sure that the tabs
face upward and outward, and the fasteners have engaged
the wall properly.
B. INSTALL THE BOILER ON THE WALL. SEE FIGURE 1.
1. Lift the boiler up against the wall, with the top edge of the jacket
slightly above the wall bracket tabs. Engage the boiler jacket near
top lip notches properly.
2. There are fastener holes in the lower area of the boiler rear
panel to ensure that the boiler does not move off the wall bracket.
Mark these 2 holes, with the boiler in place, then lift the boiler off
the wall bracket.
3. Determine which fastener type will best engage with the wall con-
struction at the location of the 2 marked holes. Drill out the appropri-
ate diameter and depth holes for the fasteners, where marked.
4. Lift the boiler up onto the wall bracket again, as described in
Step 1. Secure the boiler to the wall, with the 2 fasteners in the
lower rear panel area.
