1Introduction

Description

The ELITEC DTG 1300 Eco.NOx/V boiler is a floor-standing cast iron gas-fired boiler with an atmospheric burner with very low pollutant emission with integrated domestic hot water production. The boiler must only be connected to a chimney.
The design of the cast iron heater body with interleaved spurs gives very high performance. Also, the baffling in the smoke circuits limits the natural chimney effect and gives high performance yields.

2 Composition of the range

Heating and domestic hot water

- DTG 1300 Eco.NOx/V or H Panel B: Boiler with (110 ou 130 l) domestic hot water tank and electronic command panel

3.1 Introduction
97/23/CE Directive
The boilers are equipped with an anti smoke release safety device ; they may therefore be installed in inhabited areas. It consists of a thermostat located in the anti-blowback which causes the burner to stop for 15 minutes. This is indicated by an alarm light flashing on the control panel. The boiler automatically restarts after 15 minutes if the cause of the cut off has been removed.
The tightly packed insulation of the boiler equipment reduces losses into the atmosphere to very low levels.
- DTG 1300 Eco.NOx/V or H Panel D: Heater with (110 ou 130 l) domestic hot water tank and DIEMATIC 3 electronic command panel
The command panel gives priority to producing domestic hot water.
Gas and oil boilers with a maximum operating temperature of 110°C and hot water tanks with a maximum operating pressure of 10 bar pertain to article 3.3 of the directive, and therefore, cannot be CE­marked to certify compliance with the directive 97/23 EC.
De Dietrich boilers and DHW tanks conform to the regulations in article 3.3 of the 97/23/CEE Directive and is backed by the CE mark for the 90/396/CEE, 92/42/CEE, 72/73 CEE and 89/336/CEE directives.

1.1 Ventilation

The ventilation section, obligatory in the location where the heater is installed where there is a direct air inlet must conform with the DTU
61.1 (P45-204) standard and in particular with the instruction on general management (Book 1764, April 1982).
In order to avoid damage to the boilers, it is necessary to
prevent the contamination of combustion air by chlorine and/or fluoride compounds, which are particularly corrosive.
These compounds are present, for example, in aerosol sprays, paints, solvents, cleaning products, washing products, detergents, glues, snow clearing salts, etc.
Therefore :
- Do not suck in air evacuated from premises using such products:
hairdressing salons, dry cleaners, industrial premises (solvents),
premises containing refrigeration systems (risk of refrigerant
leakage), etc.
- Do not stock such products close to the boilers.
If the boiler and/or peripheral equipment are corroded by such chloride or fluoride compounds, the contractual guarantee cannot be applied.
