CJ/T 29-1999Water boiling gas appliance (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces CJ/T 29-2003 "Gas Water Booster". The main technical changes compared to CJ/T 29-2003 are as follows.

--- Increased appearance (see 6.1);

--- Modified the requirements for sealing (see 6.2, 5.2.1 of the 2003 edition);

--- Supplementary requirements for combustion conditions (see 6.4, 5.2.7 of the 2003 edition);

--- Modified the flameout protection device (see 6.5, 5.2.9 of the 2003 edition);

--- Increased igniter performance (see 6.6);

--- Added safety device with fan boiler (see 6.7);

--- Revised the requirements for surface temperature rise (see 6.8, 5.2.8 of the 2003 edition);

--- Added electrical performance (see 6.9, 2003 edition 5.2.21);

--- Increased the requirements for auxiliary power supply (see 6.10);

---Modified thermal efficiency (see 6.11, 5.2.6 of the 2003 edition);

--- Increased water production rate requirements for continuous boilers (see 6.13);

--- Increased the requirements for exhaust gas temperature (see 6.14);

--- Increased durability requirements for flameout protection devices, igniters, and gas valves (see 6.17);

--- Increased the boiling water temperature requirements (see 6.18);

--- Increased insulation performance requirements (see 6.19);

--- Added test methods (see Chapter 7, Appendix A of the 2003 edition);

--- Removed the standard necessity assessment (see Chapter 4 of the 2003 edition).

This standard is consistent with GB 16914-2012 "Safety Technical Conditions for Gas Burning Appliances", and Appendix A gives support for this standard.
