Installation Instructions

CONTROL DEVICE OPTIONS
The fuse or circuit breaker used must be rated for a maximum of 20
amperes (no greater than 16 amp load). If a lower rated fuse or circuit
breaker is used, it must be rated at least 25% greater than the heating
system load attached to it. If an area requires more than the 16
amperes allowed, additional branch circuits may be used, each having
its own overcurrent protection. These branch circuits may all be con-
trolled by a single thermostat if it is used with a system of electric
relays.
The selection of a control device will be determined by the designed
use of the system. If installed and used as a primary heating system, a
thermostat must be used. If designed to be used as a supplemental or
floor warming system, timers or other control devices also may be
used. The Calorique Warm Floors System can be controlled by any
standard line voltage method — including line voltage thermostats or
low voltage thermostats in conjunction with line voltage relays.
Whichever control option is used, all components must meet all appli-
cable local and national codes and be rated for use with an electrical
heating system.
FLOOR CONSTRUCTION
Joists — The Calorique Warm Floors System is designed for use with
typical wood and/or metal floor joists. The joists must have a facing
width no greater than 2 inches / 50 mm with a spacing between the
joists strips of 12, 16 or 24 inches on center / 300, 400 or 600 mm.
Floor Surface — The floor surface may be of any material having a
total thermal insulation value of less than R-11 / RSI-2 — this includes
any floor finish such as tile, hardwood, carpet, as well as secondary
materials added to the floor at a later time. Contact the material man-
ufacturer for specific information concerning the thermal insulation
factor of the material being specified.
Surface Finish — Any type of surface finish can be applied to the fin-
ished floor — the total thermal insulation value of the sub-floor and
floor finish must not exceed R-11.
DESIGN CRITERIA
NOTE
A thermostat or appropriate control must be provided for each room
in which Warm Floors is being used as a primary heat source.
NOTE
The National Electrical Code specifies that each branch circuit used in
conjunction with a heating system must be for the exclusive use of
the heating system. Do not connect lights, outlets, etc. to any branch
circuit used with the Calorique Warm Floors System.

Metal joists must be
properly grounded in
accordance with local
codes.

NOTE
Do not use the Warm Floors System to cure adhesives, stains or
paints since direct heat during curing may cause cracks or discol-
oration.

All wiring, fuses
and/or circuit break-
ers must conform to
National Electrical
Code.
