This document explains the correct procedure for the installa-
tion and safe operation of all models of Draft Barrier and Pedestal
Mounted Heaters.
Draft Barrier Heating Systems are designed to be installed in
accordance with the National Electrical Code and with local codes
by a qualified person.
General Information —
Draft Barriers and Pedestal Mounted Heaters are intended for
wall, sill or floor mounting.
The heaters are designed so that they may be used as an indi-
vidual cabinet convector, in a wall-to-wall configuration or as an
end-to-end continuous perimeter room heating system.
Draft Barrier heating systems are supported by a wide selec-
tion of controls and accessories designed to solve any heating
requirement.
Before You Unpack —
1. Make certain that the number of cartons received agrees with
the Bill of Lading, Packing List and original order. Also check
that the correct style (Model) and color have been shipped.
2. Every heater is carefully inspected and shipped with a clear
Bill of Lading.
Obvious external and/or concealed damage must be reported to
the carrier for remedy.
WARNING: — Hazard of Fire
1. DO NOT INSTALL HEATERS AGAINST ANY HIGH-
LY COMBUSTIBLE SURFACES SUCH AS LOW
DENSITY CELLULOSE FIBRE.
2. DO NOT LOCATE HEATER BELOW ELECTRICAL
CONVENIENCE RECEPTACLES.
3. DO NOT STORE OR USE GASOLINE OR FLAMMA-
BLE LIQUIDS IN THE VICINITY OF THE HEATERS.
WARNING: Hazard of Fire. The normal operating
temperatures of cabinet convectors are relatively
high and proper operation requires free circulation
of room air through the heating element. Bottom
