GT INSTALLATION AND OPERATION INSTRUCTIONS | Page 11 |
The following are important rules that must be followed when constructing the condensate system:
1.Connect the condensate trap to the drain using 1/2 in, 13 mm, silicone, rubber, reinforced nylon, or PEX tubing. Long runs must be properly pitched and supported to prevent blockage.
2.Do not use nylon tubing, as it will collapse, blocking drainage. This could damage the boiler.
3.Do not seal the opening between the condensate pipe and the condensate drain pipe, Figure 19. In the event of a blocked drain the opening will allow the condensate to overflow and prevent the boiler from flooding.
4.Never have the drain pipe higher than the hole in the back cabinet, this will flood the boiler.
5.Never allow the drain to freeze or become blocked. This will cause condensate to fill the combustion chamber resulting in a no heat condition and damage to the boiler.
6.NEVER use copper, steel, or galvanized piping in the construction of the condensate system.
7.When a condensate pump is used or required, select a pump that is designed for residential furnaces.
GENERAL PLUMBING GUIDELINES
If connecting this boiler to a system containing cast iron radiation, be sure to add a strainer to the system to trap any sediment that may dislodge. Failure to do this could harm the heat exchanger and void the warranty! The use of
CAUTION: All heating system piping must be installed in accordance with the ANSI/ASME Boiler and Pressure Vessel Code, Section IV. All applicable local codes and ordinances must also be followed. If the boiler is installed above any radiation elements it must be fitted with a low water cutoff device installed above the normal boiler water level!
CAUTION: This boiler must have adequate water flowing through it whenever the burner is on. Failure to do this will damage the unit and void the warranty!
CAUTION: All systems must be flushed to remove sediment, flux, filings and other foreign matter. Use products such as Fernox “Superfloc” for new installations and CHR “Central Heating Restorer” for retrofits. Also add an inhibitor to the system water to prevent limestone and magnetite deposits from forming and to protect the boiler from galvanic corrosion. An inhibitor such as CHP, “Central Heating Protector” from Fernox is recomended.
If connecting this boiler to a system containing cast iron radiation, be sure to add a strainer to the system to trap any sediment that may dislodge. Failure to do this could harm the heat exchanger and void the warranty!
The use of
CAUTION: The boiler fittings cannot support any weight. The plumbing system must be supported by the building structure. A wrench must be used to hold the boiler fittings when installing the heating system piping. Failure to do so can seriously damage the boiler, voiding warranty!
The GT hot water boiler comes from the factory ready to be piped to the heating system. The boiler must be used only in a Primary/Secondary pumping system to avoid cycling problems in systems that have poor fl ow or heating zones with very small capacities.
CAUTION: A 11⁄4 in, 32 mm, primary loop system must be used for
A11⁄2 in, 38 mm, primary loop system must be used for the
