CGTH INSTALLATION, OPERATION AND SERVICE MANUAL

4.14 Grille Installation (for Select Models Only)

A protective grille is included with select models of the CGTH-Series heater. This grille is supplied in sections and must be installed on the underside of the reflector prior to operation.

Grille sections are held in position by a channel formed by the rolled edge of the reflector. The shorter length 8' (2438 mm) heater requires installation of two protective grille sections, while the longer heater (11' 6") (3505 mm) requires three protective grille sections.

Grille Section (P/N 08050001) is open-ended and installed along the length of the reflector. Grille End Cap (P/N 08050002) is the formed end cap and is installed at the end of the grille that is furthest from the burner.

Installation:

Step 1. Silicone Cap Installation (See Figure 12).

Silicone caps (P/N 91915951) are to be placed along each side of the grille at both end fingers and the center finger.
