2.3 National Standards and Applicable Codes All appliances must be installed in accordance with the latest revision of the applicable standards and national codes. This refers also to the electric, gas and venting installation. Note: Additional standards for installations in public garages, aircraft hangars, etc. may be applicable. SECTION 3: CRITICAL CONSIDERATIONS SECTION 3: CRITICAL CONSIDERATIONS 3.1 Required Clearances to Combustibles Clearances are the required distances that combustible o

The T and Fork layouts have a tee or cross (called the "last tee" or "last cross") where the combustion gases in the system enter the tee or cross with directly opposing flow directions, which creates an added source of pressure drop in the system. This additional source of pressure drop requires some difference in how the allowed manifold length is calculated. In this case, we have to differentiate manifold tube that is located between the radiant pipe and the last tee (or cross) from manifold

• In shops, offices and other sections of aircraft hangars communicating with aircraft storage or servicing areas, heaters shall be installed not less than 8' (2.4 m) above the floor. • Suspended or elevated heaters shall be so located in all spaces of aircraft hangars that they shall not be subject to injury by aircraft, cranes, movable scaffolding or other objects. Provisions shall be made to assure accessibility to suspended heaters for recurrent maintenance purposes. and B149.2: Installation

The tube and accessory packages contain enough tube, reflector and hanging parts for one unitary CTHN heater. Elbows, u-tubes, controls, and any other parts must be purchased separately. Table 5: Unitary Heater Design Requirements Burner Model: CTHN-40 CTHN-60 See Page 14, Figure 13 for a general overview of a CTHN unitary heater. CTHN unitary heaters are controlled by thermostat. Table 5 summarizes the design requirements for a CTHN unitary heater. CTHN-80 CTHN-100 CTHN-125 CTHN-150 CTHN-175 CT

Reflectors can be used over the manifold tube but are not required. The system design parameters are such that the manifold sections are not subjected to condensate when the system is fully heated up. It is required that heat-treated aluminized or coated tubing is used for the manifold to increase system life and to handle initial condensation during start-up. Damper couplings may be necessary to balance system vacuum. Design requirements for a CTHN multiburner system are summarized on Page 30,

SECTION 6: SUGGESTED LAYOUTS SECTION 6: SUGGESTED LAYOUTS The following are suggested layouts for the heater. These layouts are effective in maximizing the heat pattern and overall performance of the heater. All heaters can be common vented or individually vented (See Page 34, Section 9) depending on the building requirements. These are only suggested layouts. The heater can be designed in various configurations provided they are in the guidelines of this manual. When designing a U-Tube or Elbow
