LTS SERIES - INCLINED MOUNTING INSTRUCTIONS

These inclined mounting instructions relate to LTS series heaters (straight tubes) that do not utilize the elbow
accessory. These heaters have been tested and design certified by the CSA for 2"/12" pitch (10º) inclined
mounting of the heater from the control box to the draft inducer assembly as shown in the following diagram.
The purpose of this type mounting is to allow the heater to be mounted in the plane of the roof (particularly in
modern "Butler" type buildings frequently used today). This will typically put the heater out of the way while still
providing the warmth and comfort. The heater can be inclined upwards from the control box to the draft inducer
at a distance of 2 inches up for every linear foot of the heater length. The total rise for each draft inducer is
tabulated in the table below:
