G. Exhaust Requirements:

a. Direct Vented gas fired infrared heating system installation will comply with the

manufacturer’s installation instructions, the current National Natural Gas and Propane

Installation Code and all applicable local codes using:

i. A 4 inch (100 mm) vent pipe of a gauge prescribed by national and/or local codes

ii. Two heaters may be common vented using a 4 inch x 4 inch by 6 inch (100 mm x

100 mm x 150 mm) vent tee as supplied by the manufacturer; common vented

heaters will be controlled by one common thermostat

b. Indirect Vented Installation in Canada:

i. Gas fired infrared radiant heating system installation will comply with the

manufacturer’s installation instructions, the current national Natural Gas and Propane

Installation Code B149.1 and all applicable local codes.

ii. The gas fired infrared radiant heating system will be provided with mechanical

ventilation at a rate of 300 cfm for each 100,000 Btuh system input or fraction thereof.

The ventilation system will be interlocked so that any reduction of the ventilation rate

will cause the shutdown of the interlocked heater or group of heaters.

c. Indirect Vented Installation in the USA:

i. Gas fired infrared radiant heating system installation will comply with the

manufacturer’s installation instructions, the current National Fuel Gas Code, ANSI

223.1 standards, and all applicable local codes.

ii. Natural or mechanical exhaust will be provided for the gas fired infrared radiant

heating system at a rate of 4 cfm for every 1,000 Btuh of natural gas system input, or

at a rate of 5 cfm for every 1,000 Btuh of propane gas system input.

H. Electrical Requirements:

a. Power supply wiring (115Vac, 60Hz, with a current rating of no less than 1.5A at 115Vac)

will connect to the heater as per the wiring diagram in the manual supplied by the

manufacturer.

Part 3 — Performance

3.01 Combustion

Heater will ensure controlled combustion with complete conversion of fuel and clean combustion

with resultant combustion products C0

, H

O, O

and N

and will produce a limited volume of

noxious component & AFCO (< 350 ppm)

3.02 Safety

a. Clearances to combustibles in all directions will be defined individually per heater model in the

Installation and Owner’s Manual as certified by UL Laboratories of Canada

b. Clearance to combustibles for horizontal or angle mounting as certified by UL Laboratories of

Canada will not exceed those listed in the Installation and Owner’s Manual for the Rinnai

model HE+ Series.

3.03 System Efficiency / Energy Consumption

System efficiency and annual energy consumption of heating systems of heaters of this type and

comparison to other heating systems will be calculated acc. prEN 15316 to fulfil the requirements

of the EPBD (Energy Performance of Building Directive).
