HYDRONIC SYSTEMS CONNECTIONS
The Model HP-M2-Series may be used as either a Paloma
Pak/Hytech boiler replacement or as a new wall-mount installation. Carefully unpack HP unit. Read all installation
instructions before starting the installation. Remove the Front
removable jacket and find the plumbing accessories package inside the unit.
The HEATMAKER HP-M2 Series is supplied with the necessary fittings to match the Paloma Pak supply and return piping.
If the original wall bracket is compatible with the slotted
mounting holes on the rear of the HP-M2, the supply and return
pipe unions attach directly to the existing piping. If the
installation is new or if the old bracket is incompatible or
unusable, the return and supply connections will require repiping to match the HP-M2 connections.
WALL MOUNTING INSTRUCTIONS
PALOMA/HYTECH REPLACEMENT
Hang the HP-M2 as assembled from the manufacturer onto
the existing wall bracket. Do not remove the brackets which
are attached to the new unit. If the existing wall bracket does
not align with the slotted mounting holes on the rear of the HPM2, remove the old bracket from the wall and follow instructions
for new wall mount below.
PLUMBING ACCESSORIES INSTALLATION
NEW WALL MOUNT INSTALLATION
Remove the bolts, nuts and washers that secure the two
mounting brackets to the bottom and rear of the HP-M2
cabinet. Remove the U-channel spacer bracket from each
wall bracket and discard. (Spacer brackets are used only with
original bracket in Paloma Pak/Hytech retrofit installations)
1)
Attach boiler drain plumbing accessory to the labeled
“return” on the bottom of the HP-M2.
2)
Separate Thermostatic Union Assembly halves and
thread the 1" nipple side to the labeled “supply” on the
bottom of the HP-M2. Attach the remainder of the union
assembly onto the top half of the union. Be sure to use
appropriate thread sealers to assure leak-tight joints.
3)a. Where the HP-M2 is a direct replacement for a Paloma
Pak/Hytech the installation is completed by connecting
union halves together.
b. If the installation is new, refer to the piping schematics
and instructions on page 10 -12.
Attach the included mounting template to the selected wall
location. Mark and drill holes for appropriate mounting hardware at the template specified locations. Remove template
from the wall and securely affix the two wall brackets to the wall
surface with appropriate mounting hardware (provided by
installer).
GAS SUPPLY CONNECTION
If the installation is a direct retrofit, the gas supply will require
re-piping to connect to the HP-M2 gas inlet. If the gas is
supplied from below the unit, be sure to run supply pipe to a
point higher than the vent center line before connection to the
unit gas valve.
Lift the HP-M2 onto the wall brackets and re-assemble the
bolts, nuts and washers to affix the unit onto the wall brackets.
NOTE: DO NOT REINSTALL THE U-CHANNEL SPACER BRACKETS WHEN MOUNTING THE WALL BRACKETS DIRECTLY TO
A WALL.
On new installations refer to the gas piping section for gas
pipe sizing and related information.
