Krok 6. Prívodné plynové potrubie
POZNÁMKA: Plynovú prípojku vám môže nainštalovať
len oprávnená osoba podľa požiadaviek noriem a plat-
ných predpisov.
POZNÁMKA: Pred prvým zapálením krbu by mal byť
z prívodného potrubia vypustený všetok prípadný za-
chytený vzduch.
NOTE: Consult local building regulations to properly
size the gas supply line leading to the (Rp 1/2 in.)
hook-up at the unit.
This threaded gas inlet connection is ISO 7-Rp 1/2 (BSP
Rp 1/2).
To install the gas supply line:
• Locate the gas line access hole in the outer casing of
the fi replace.
• The gas line may be run from either side of the fi replace
provided the hole in the outer wrap does not exceed 51mm
(2 in.) in diameter and it does not penetrate the actual
fi rebox.
• Open the fi replace lower grille, insert the gas supply line
through the gas line hole, and connect it to the shut-off
valve.
• When attaching the pipe, support the control so that the
lines are not bent or torn.
• After the gas line installation is complete, all connec-
tions must be tightened and checked for leaks with a
commercially-available, non-corrosive leak check solu-
tion. Be sure to rinse off all leak check solution following
testing.
!
WARNING: DO NOT USE AN OPEN FLAME TO
CHECK FOR GAS LEAKS.

• Insert insulation from the outside of the fi replace and pack
the insulation tightly to totally seal between the pipe and
the outer casing.
• At the gas line access hole the gap between the supply
piping and gas access hole can be plugged with non-
combustible insulation to prevent cold air infi ltration.

Step 7. Gas Pressure Requirements
Pressure requirements for Heat & Glo gas fi replaces are
shown in Table 1 below.
A tap is provided on the outlet side of the gas control for a
test gauge connection to measure the manifold pressure.
To measure inlet pressure, provisions must be made to
attach a test gauge to the tap immediately upstream of
the gas supply connection to the fi replace.
The fi replace and its individual shut-off valve must be
disconnected from the gas supply piping system during
any pressure testing of the system at test pressures in
excess of 60 mbar.
If the fi replace must be isolated from the gas supply piping
system by closing an individual shut-off valve, it must be
of the handle-less type.
