Figure 19: Firewall Plates
1. There are two different types of firewall plates
identified as "Front" and "Common". All builds start
with one (1) "front" firewall plate and "common"
firewall plates are added as the boiler grows in size.
Models V1104H and V1106H Only. Cut-off 3/4" of
excess material from rear edge of firewall plate to
eliminate interference with rear target wall.
Model V1104H: Remove excess from front firewall
plate.
Model V1106H: Remove excess from common
firewall plate.
Modèles V1104H et V1106H uniquement. Coupez
3/4 po de l'excédent de matériau du bord arrière
de la plaque de pare-feu pour éliminer les
interférences avec la paroi arrière de la cible.
Modèle V1104H: Retirez l'excédent de la plaque
pare-feu avant.
Modèle V1106H: Retirez l'excédent de la plaque
pare-feu commune.
2. Firewall plates have two (2) notches located along
the bottom edge which interlock with lugs cast on
each center section, making them self positioning.
The "front" firewall plate must be positioned as far
forward as possible.
3. Install firewall plates using silastic (provided) on
each upper and lower edge of firewall plate where
plate rests against section. Apply a minimum bead
of 1/2" diameter to all contact points to form a good
bond to the casting.
