AirHeat, V1, Operating Instructions, Edition 09.12

Ignition

Ignition voltage should be 6000 VAC.

Approval of Components

Limit Controls & Safety Equipment

All limit controls and safety equipment must comply with

all applicable local codes and/or standards and must be
listed for combustion safety by an independent testing
agency. Typical application examples include:

• American: NFPA 86 with listing marks from UL, FM, 

CSA

• European: EN 746-2 with CE mark from TuV, 

Gastec, Advantica

Electrical Wiring

All the electrical wiring must comply with all applicable

local codes and/or standards such as:

• NFPA Standard 70
• IEC60364
• CSA C22
• BS7671

Gas Piping

All the gas piping must comply with all applicable local

codes and/or standards such as:

• NFPA Standard 54
• ANSI Z223
• EN 746-2

Where to Get the Standards:

The NFPA Standards are available from:

Duct Design and Burner Mounting 

Duct Design 

See Figure 3 for typical mounting arrangements and duct
designs.

Support

The mounting flange or brackets supplied with an AH
burner are capable of supporting the weight of the burner
and blower. The AH burner case itself is designed to
support the weight of the blower, so the blower does not
require independent support.

Valve Train Support

Support valve trains independently of the burner.

Gas Piping 

Use flexible nipples to allow for thermal expansion of the
burner.

Check Valve Piping

Gas flow through the check valve must be horizontal. See
Figure 1.
