WARNING
Gas supply shall be shut-off and the electrical power
disconnected before proceeding with the conversion.
Failure to do so could result in fire, explosion, electrical
shock, or the unit starting suddenly resulting in injury.
2-POINT MOUNTING KIT
Model Application
On occasion, building structures may not easily accommodate
the standard four-point unit suspension on HD/HDS (100 &
125 only), PTC (85-310 only), PTS, PTP, PDP (350 &400)
models. For those cases, Modine offers a two-point mounting
conversion kit, which can be used to convert the unit to two-
point suspension. The conversion kit includes two heavy
gauge "C" channel brackets and two angle brackets, along
with required fasteners to attach the brackets to the heater.
To ensure adequate suspension of the unit is achieved, follow
these instructions in detail. For complete unit installation
instructions, please refer to the latest revision of the
Installation & Service Manual that shipped with the unit.
These are summarized in Table 1.1.

INSTALLATION – 2-POINT MOUNTING KIT ACCESSORY
Assembly/Installation
The recommended procedure for assembly and installation is
described as follows (refer to Figures 2.1 and 2.3):
1. Attach both "C" Channel Brackets to the existing unit
suspension holes using the hardware supplied with the
mounting kit. Each bracket is attached using (2) 3/8"-16
x 1” hex head machine bolts and (2) 3/8” flat washers.
Refer to Figure 2.1.
Figure 2.1 – “C” Bracket Installation
2. Attach one of the angle brackets to the top of each “C”
channel. Each angle bracket is attached using (3) 1/2”-
16 x 1-1/2” hex head machine bolts, (3) 1/2” flat washers,
(3) 1/2” lock washers, and (3) 1/2”-16 nuts. Refer to
Figure 2.2. Hand tighten the nuts to allow unit balancing
in Step 4.
3. Ensure that the vertical supports (Unistrut P3000T or
equivalent, by others) from which the unit will be
suspended are plumb and rigidly supported. Raise the
unit to its mounting position and align the angle brackets
with the vertical supports as shown in Figure 2.3. Fasten
the angle brackets to the vertical supports (fasteners are
by others).
4. After securing the unit to the two vertical supports,
ensure that the unit is level both front to back and side to
side. The slotted mounting holes in the “C” channel
allow the unit to be moved forward or backwards until it is
level front to back. To level the unit side to side, ensure
the angle brackets are connected to the vertical supports
at the same height. Once the unit is level, tighten the
nuts from Step 2.
5. Continue with the gas, electric, and venting installation
instructions listed in the I&S Manual that shipped with the
unit. Be sure to follow all cautionary notes. Re-check
that the unit is level and that nothing has shifted once the
installation of the unit has been completed.
