Install the Copper Brute heaters in accordance 

with the procedures in this manual (or the warranty 

may be voided), local codes and ordinances. In the 

absence of such codes, install the heaters in accordance 

with the latest edition of the National Fuel Gas Code, 

ANSI Z223.1. In Canada, the installation must be 

in accordance with CAN1-B149.1 or .2 and local 

codes. The authority having jurisdiction may require 

the installation conform to the Standard for Controls 

and Safety Devices for Automatically Fired Heaters, 

ANSI/ASME CSD-1. Any changes to the heater, gas 

controls, gas orifices, wiring or draft diverter may void 

the warranty. If field conditions require a change to 

any of the above, consult the factory. 

All gas-fired products require correct installation 

to assure safe operation. The requirements for heaters 

include the following:
1.      Field assembly of drafthood or vent cap (see 

Section 2.2).

2.      Appropriate site location (clearances) and 

flooring.

3.      Sufficient combustion and ventilation air.
4.      Adequate venting of combustion products.
5.      Adequate water flow.
6.      Properly sized gas meter and piping.
7.      Proper electrical wiring.

This manual provides the information needed to 

meet these requirements. Review all application and 

installation procedures completely before continuing 

the installation.

factory with the top assembly in the low-profile 

configuration for outdoor installations.

for indoor installation when equipped with a 

special drafthood, which must be installed without 

modification. The part number for the drafthood is on
