Figures 2.1 and 2.2 illustrate the more commonly
used methods for heater mounting.  Figure 2.1
shows the fastest and most economical method.
Some local codes or application conditions, such
as drafts that could cause units to swing,
stipulate that if flexible gas connectors are
used then the heaters must be rigidly mounted
(Figure 2.2)

Heater must be level from side to side (see Figure
1.2 on pg. 3).  The units must be mounted at a
20° to 35° angle from horizontal
, so the controls
(or manifold end) are located at the lower end
(Figure 2.3-2.5). Gas and electrical lines must not
be located above the path of exhaust.
