Provisions shall be made to assure accessibility to suspended heaters for recurrent maintenance purposes. and B149.2: Installation Codes for Gas Burning The heater must be electrically grounded in accordance with the following codes: United States: Refer to National Electrical Code®, ANSI/NFPA-70 - latest revision. Wiring must conform to the most current National Electrical Code®, local ordinances, and any special diagrams furnished. Canada: Refer to Canadian Electrical Code, CSA C22.1 Part 1 - latest revision. 4.4 Electrical The venting must be installed in accordance with the requirements within this manual and the following codes: United States: Refer to NFPA-54/ANSI Z223.1 - latest revision, National Fuel Gas Code. Canada: Refer to CAN/CGA B149.1 and B149.2: Installation Codes for Gas Burning Appliances. 4.5 Venting These heaters are approved for installations up to 2000' (610 m)(US), 4500' (1370 m)(Canada) without modification. Consult factory if US installation is above 2000' (610 m) or Canadian installation is above 4500' (1370 m). 4.6 High Altitude CTHN-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL SECTION 5: HEATER DESCRIPTIONS 5.1 Unitary vs. Multiburner CTHN-Series burners may be used for unitary heaters or for multiburner systems. Unitary heaters consist of a single burner, a single run of radiant tubing and a single fan assembly. See Page 14, Figure 13 or See Page 17, Figure 16 for details. Multiburner systems consist of more than one burner and more than one run of radiant tubing. The runs of radiant tubing are connected together by manifold tubing. The manifold tubing connects to a single pump that exhausts the flue gases outdoors. See Page 32, Figure 19 through Page 35, Figure 23 for common multiburner system layouts. Since this manual addresses installation of both unitary heaters and multiburner systems, pay close attention to section and figure titles to verify relevance to unitary heaters or multiburner systems.

CTHN-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL 10 SECTION 7: GENERAL SUSPENSION DETAILS To ensure your safety and comply with the terms of the warranty, all units must be installed in accordance with these instructions. The gas or the electrical supply lines must not be used to support the heater. Do not locate the gas or electric supply lines directly over the path of the flue products from the heater. The heater must be installed in a location that is readily accessible for servicing. The heaters must be installed in accordance with clearances to combustibles as indicated on the rating plate and in this instruction manual. The minimum and maximum gas inlet pressures must be maintained as indicated on the rating plate.Typical installation configurations are shown in Figure 12.
