6. Units with a VUR-1 or HR-3 vertical – upblast discharge arrangement must have discharge ductwork sup-
ported from building support members and not supported from the equipment. NO DISCHARGE DUCT-
WORK IS TO BE SUPPORTED BY EQUIPMENT DISCHARGE OPENING CONNECTIONS.
NOTE: On indoor units, intake hood and birdscreen and any appropriate ductwork must be full size of unit
opening.
b. Outdoor Units – See Figures No. 1 and No. 2.
1. Prior to assembly of unit sections or accessories, caulking must be applied to the flat surfaces where
the pre-punched fastener holes are located (See Figures No. 1, 2, and 10) on each section. Caulk pe-
rimeter of opening to make connection watertight.
2. Units with a vertical – upblast discharge arrangement must have discharge ductwork supported from
building support members and not supported from the equipment. NO DISCHARGE DUCTWORK IS
TO BE SUPPORTED BY EQUIPMENT DISCHARGE OPENING CONNECTIONS.
Connect discharge air duct or discharge grill to unit outlet. If unit is installed outdoors, be sure that duct
opening to building is adequately flashed and sealed to prevent leakage. All air to the heater must be
ducted directly from the outdoors. Recirculation of room air is not permitted. Adequate instructions
shall be provided to address heater installations where a duct work system is attached to the inlet of the
heater to purge the volume of the duct system with at least four air changes prior to an ignition attempt.
If in doubt regarding the application, consult the heater manufacturer.
7. Remote Control Panel
a. Standard remote control panel: This panel is furnished with two heavy duty toggle switches and three 115
volt signal lights. The switches control the blower (blower switch) and the burner (season switch). The signal
lights indicate supply blower operation (white light marked blower), burner operation (amber light marked
heating), and safety lockout (red light marked lockout). See typical remote control panel illustrated in Figure
No. 8 in this manual.
b. Optional remote control panel(s): Same as described above but with the addition of lights and switches de-
pending upon options ordered.
8. Remote Control Panel Specifications
Signal Lights: Pilot lights are rectangular neon type for 115 V.A.C. service. Lights are UL approved and have 18
AWG 16/30 standard 105° C plastic wire leads. Bezel is chrome finished.
Switches: On-Off and On-Off-ON switch action with screw terminals. Rated at 15 AMPS at 115 V.A.C. service
with 3/4 HP rating at 115 V.A.C.
Lids and Cover: Remote control panel lids are 16 gauge brushed stainless steel. 1/8” high letters are screen
painted using Wornoy Duwell Enamel series 10-000 ink. Wiring box dimensions are 8” x 5” x 3-1/2” deep.
Terminal Blocks: Blocks are medium duty 15 AMP screw type. All terminals are numbered according to corre-
sponding wiring diagram.

9. Remote Control Panel Installation
a. Refer to Figure No. 9.
b. Align box with spirit level.
c. If box is to be surface mounted, three (3) mounting holes in back of box are recommended. One in each top
corner and one at bottom center.
d. If mounting holes are to be located in side of box as shown, four (4) holes are recommended. Two at top and
two at bottom.
e. If wiring box is to be recessed, install so that open edge of box will be flush with finish wall. Install optional
flush mounting wall plate.
f. Examine wiring box and control panel for clearance before providing conduit hole(s)
g. All wiring must comply with applicable electric codes.
h. Control panel is furnished with components wired to coded terminal strip. Installer to connect numbered ter-
minal blocks on remote control panel to corresponding terminal block(s) in master control panel on unit.
