The Electro-Mate is designed with a special double plate at the element mounting. Cool air from the
blower must blow between these two plates. Therefore, the Elector-Mate must be inserted into the base
plenum such that the mounting plate is even with the edge of the hot air outlet hole. Do not necessarily
line up the Electro-Mate control box with the furnace cabinet front. The concern is the hole in the bottom
of the furnace mating with Electro-Mate elements.
Cutting the correct hole size in the plenum
– locate the supplied cutout template marked “UAI012”. Once
placement of the Electro-Mate is determined, tape all four corners of the template to the plenum. Make
sure that the template is squared off to the plenum before proceeding to the next step. Using a
utility knife cut out the appropriate dashed line on the template. Then use a marker to trace around the
area cut out of the template. Remove the template from the plenum and proceed to cut the hole into the
plenum.
Extend the “V” channel to butt against the plenum surface opposite the 8”x18” hole. After Electro-Mate
insertion, a sheet metal screw may be installed to attach the back plate of this “V” deflector channel.
Insert the Electro-Mate and properly screw to base plenum. If the base plenum is 18” wide, side supports
will be needed on the side for proper attachment to the Electro-Mate.
Special Hi-Limit Probe Installation
Shipped loose with this unit is a hi-limit probe which must be installed under the electric elements
(counterflow). This is shown on drawing EA104. This hi-limit probe must receive direct heated air from
the electric elements. It is wired into the red/white hi-limit loop as detailed in the “ELECTRICAL
HOOK-UP” section of this manual.
WarmFlo Supply Sensor Installation
Notice spacing and positioning comments on drawing EA104. Basically this sensor needs to be in a
major air stream, about 20 airflow inches away from the actual electric element.
ELECTRICAL INSTALLATION
This manual applies only to the 240 power wiring. See WarmFlo controller manual, HI320, for all
control wiring.
The Electro-Mate nameplate lists the continuous amp draw for the model you are installing. Based upon
NEC requirements and/or local codes, supply and route an appropriate 240VAC size cable or power wires
between the electrical panel source and the Electro-Mate inside circuit breakers, use only copper
connected to breakers. If you would like to feed the Electro-Mate breakers using one feed you must order
the optional bus bars listed below:
15 and 20 kW models EM-5716
25 kW models EM-5717
Grounding – route and install the appropriate size conductor wire between the Electro-Mate lug labeled
“ground” and the building service entrance panel ground bus. This must be a conductor wire sized
according to the total amp rating of the Electro-Mate. The conduit is not a sufficient ground conductor.
